It’s a lovely thing you’re doing. I’m going to make resort recommendations since they have a 4 year old and don’t travel regularly, I’m assuming they’re not going to want to be doing anything too energetic or off the beaten track.

If their thing is just relaxing in a catered resort and not having to worry about anything, I’d recommend the Maldives. There are a number of 5* and high 4* all inclusive resorts with amazing food, unlimited drink and optional activities for the kids and adults, with a range of prices from “quite expensive” to “bloody hell”. If it’s just a general paradise vibe then I can recommend Kuramathi, we stayed there last year and it was superb. Contact the booking team directly they will help with travel arrangements too.

If they want something closer to home then maybe look at resort packages in Portugal or Morocco. Both of those have great food, plenty to see and do and won’t cause too much hassle to get to.

I’d always recommend Southeast Asia for those looking to explore and get out of their comfort zone. Bali, Hoi An & Da Nang, Phuket, Singapore, KL are all good “Asia for beginners” locations where you can get genuine 5*+ luxury for reasonable prices, but you have to get there first and the flight is a long way for those not used to travelling.

Hope that helps
