We are going to Florida this summer and hoping for the best with ds1 who will be 6! We took him to Disneyland Paris when he was 3 and he absolutely loved it (and has always loved Legoland) so I'm hoping it's a safe bet.
We would have taken him earlier but his eating was so restricted that we couldn't see any way it would have been possible at the time but now, touch wood, there's been quite an improvement so hopefully even if he has to have burgers and fries every day he'll survive!
He's moderately to severely ASD and largely non verbal, so we can't prepare him for what's to come but he is very sensory seeking so should love the rides, the crowds, the noise, the lights, all of that gubbins. Not sure we'll be able to do much stuff in the evenings though as he wakes super early and so is very tired by 8pm or so but that won't be the worst thing in the world. In fact, re the parks I'm actually much more worried about ds2, age 3 (NT) who is the biggest wuss on the planet (still won't brave it into the baby slide in our local playground)...am anticipating DH having a whale of a time on various hair raising rides with DD and DS1 while I cuddle ds2 from a safe distance!
The pass to help with queuing will be a lifesaver. I'm just praying that Virgin can help us out a bit somehow as I'm
anxious re the airport queues and keeping him in his seat on the flight! Hopefully bringing an extra battery charge for his iPad should help.
The whole thing is a v expensive gamble but if all goes well it should be a family holiday that all 3 kids will love, and that they can all share in with the huge excitement and sensory overload!
