I took the entire family to the beachfront Greek island holiday resort where the cast of Mamma Mia! stayed

“TONY ‘the Slugger’ Rizzo, boss of New York’s Castelli crime family, wiped the blood off the baseball bat with the dead guy’s toupee…”

“Grandad!” 

“ . . . He jabbed a finger at his late accountant and shouted: ‘See what happens when you double-cross me, you muthaf . . . ’ ”

“Grandad!!”

“ ‘. . . and you gone and got your blood all over my freakin’ money. So now I gotta waste my day laundering it!’ . . . ”

“GRANDAD!!!”

I am lying on a beautiful Greek beach, a good book in my hand and a cold Mythos beer on the table beside me.

It’s holiday perfection, but someone keeps interrupting.

Two-year-olds . . . it’s all about them, isn’t it?

My wife and I are in Skiathos with our daughter and her husband and our granddaughter Flo.

We’re on one of those multi-generational breaks — or as we grandparents call it, a working holiday.

(“Just off to the spa. Can you look after Flo?” “Can Flo stay with you while we go into town?” “We thought we might have dinner on our own tonight. Just the two of us . . . ”)

Luckily, we are at the Princess Resort, a wonderful hotel just 20 minutes from the island’s airport that knows how to help families relax — especially grandparents who have forgotten what holidaying with a toddler entails.

We first came here about 15 years ago, when my daughter and her brother and sister were young, and had one of our best ever family holidays. I didn’t get much reading done then either . . . 

The hotel may be the most famous on the island thanks to Mamma Mia!.

The cast stayed here during filming and Colin Firth loved it so much, he came back the next year.

You can see why. It is located in beautiful, manicured gardens in the sheltered bay of Agia Paraskevi.

Rooms are in a two-storey building in a semi-circle which means everyone gets a view of the beach.

And what a beach! A long stretch of immaculate golden sand with shallow, warm water gently lapping up against it. It’s the perfect setting for one of the big ambitions of our holiday: Operation Get Flo Swimming.

Flo loves going to the pool at home in Brighton and is just learning, but what would she make of the sea?

After some initial reluctance caused by the feel of the sand between her toes and several swallows of salty water, she soon takes to it.

And, naturally, it’s grandad she wants to keep going in with her for a splash about.

The beach’s sun loungers and tiki umbrellas are all reserved for guests and free but you can shell out on a cabana.

OK, this isn’t cheap at €90 a day but it is definitely worth it, especially with a baby or toddler. We were in Skiathos in June and, God, it was hot.

With a cabana you have a proper base on the beach in the shade where you can snooze, eat and read (yeah, right).

It’s vital when you are trying to keep a little one from getting sunburned.

The Princess Resort is great for children. There’s a complimentary kids’ club, the Little Seals Club, a superb outdoor play area and a €15-a-night babysitting service. (Now they tell me.)

Plus, a lot of the equipment you need — from high chairs and potties to car seats and even prams — is available from reception.

(Don’t even bother asking about the fuss we had packing for a holiday with a toddler.)

But, adults need a break, too, you know, and the hotel offers scuba diving, horse riding, water sports and fishing and sailing trips. Or you can just kick back and take advantage of the massages and beauty treatments in the spa.

The Princess Resort is B&B, which means you are not tied to the hotel for dinner.

But make sure you eat at Ammos, the hotel’s taverna on the beach, which specialises in fresh seafood.

It’s not cheap but the location and grub is definitely worth it. And they love kids.

As do the staff at the superb Platanias Taverna & Bar over the road from the hotel.

It’s a good value family-run restaurant serving traditional food, where children can run free while indulgent staff manoeuvre around them without complaint.

It would be Jan Leeming’s restaurant nightmare.

For an upmarket, foodie experience head to the waterfront Baracoa about ten minutes away from the hotel by taxi.

It’s expensive, but the setting and menu have made it one of the must-visit places to eat on Skiathos.

Oh, and for a meal WITHOUT nippers, try the Princess Resort’s sister hotel, the boutique adults-only Aegean Suites Hotel, just outside town. Amazing food and terrific views over the old marina.

One of the great things about Skiathos is that you don’t need a car.

There’s a bus stop right outside the Princess Resort and the fare into town is just €2.

Or splash out €40 and get a boat ride from the jetty along from the hotel and arrive in town in style.

A word of warning, though — taxis can be thin on the ground in Skiathos Town in the evening. So if you are planning a late return, get a cab into town and arrange a return pick-up with the driver.

There are plenty of upmarket boutiques, bars and restaurants to discover in this beautiful whitewashed island capital.

It’s great to sit on the waterfront with a beer and watch the boats come and go.

And not much beats wandering around the narrow alleyways and coming across some enticing looking bar or a cafe serving delicious Greek treats.

Watch out for the scooters, though.

Since Mamma Mia! was filmed in the Sporades islands, Skiathos Town has definitely moved upmarket and it is a lot busier — even though most of the movie locations are on Skopelos and Alonissos.

But it retains a friendly, down-to-earth vibe you simply don’t get in the A-list hangouts of Santorini and Mykonos.

Anyway, after a long, tiring day of exploring in Skiathos Town, Flo’s finally in bed — so at last I can get some serious reading done.

Here we go: “It was Peppa Pig’s birthday and Daddy Pig had a great idea . . . ”
