@knitnerd90 I suspect from your throwaway sentence about Cancun that you don’t really know much about that part of Mexico! It is fabulous. My first tip though would be to get straight out of Cancun. After that, you’ve got the archaeological sites of Chichen Itza, Uxmal, Tulum, Coba (and more if you are prepared to travel further afield.) You’ve got old colonial towns like Valladolid and Merida - which is worth a couple of nights on its own, and from there you can make the trip out to Celestun to see the flamingos on a boat trip round the lagoons and mangroves. Or you can head south from Tulum into the Si’an Kaan Biosphere and see wild dolphins and manatees, crocodiles if you want to go looking for big things with teeth, eagles and other bird life, and then take the boat out into the sea and look for eagle rays and turtles. We saw turtles hatching on the beach while we were having dinner at a beachfront restaurant one night. And if theme parks and eco parks are more your thing, you can go to Xel ha for the snorkelling and lazy rivers, zipwiring at Xplor, to the native animal zoo at Xcaret. Then there are the cenotes, a different one for every day of the year, and all a different vibe from each other - one might have a zip wire, another might have terrapins swimming in it, another you might be able to swim into a cave and see fossils in the rock ceiling. And there’s a monkey sanctuary, islands to sail to, reefs to snorkel on, whale shark spotting boat trips, the vast underwater art museum. And the local food, and nightclubs if that’s your thing. Only someone who had either never been or really didn’t make the effort would think Cancun is just resorts and not worth the effort from the U.K.!
But anyway, it’s a 10.5hr LH flight away for the OP, so probably not as good an option as somewhere else. Also a lot of the attractions above are really only worth it with an older child, although I know a lot of people who’ve just enjoyed the resorts with the odd day trip out.
@flawless29 if you are looking for somewhere with a bit of culture that’s not too long a flight away and you haven’t been to Greece or Italy yet, I can highly recommend them while you children are young. Shorter flights, sea still lovely and warm, baby friendly people, and loads to see and do. If you are really after some more exotic culture but don’t want to flight too far, and you have a slightly more robust approach to the state of the world (and I’m assuming you do given your first suggestions of Egypt or India) have a look at Jordan, but November not August (will be baking in August.) Lots of culture and natural spectacle there. When I went we flew into Amman and saw the sights up there (Jerash, Dead Sea - don’t take your baby in that! Various crusader castles, etc) then headed down to Aqaba (3 hours away, but taxis cheap enough for air conditioned private car each way) for a few days on the beach, we stayed in Tala Bay Movenpick. Cheap and civilised, and very family friendly. From there you can scuba, or take trips out to Petra and Wadi Rum.
