Sonners tips are great so not got much to add - we went with our nearly 3.5 and 5.5 over NY for 4 days and loved it (tho it was *bitterly* cold!!):
- Make sure you do book the restos in advance as the last thing you want to do after queuing for rides is queue for lunch. Our faves were Cafe Mickey as characs are always there (we saw micky, goofy, winnie the pooh, piglet, eeyore and the mice from cinderella); Blue Lagoon (would be love and cool away from the summer sun, its kinda of an indoor fake island thing, decent food); breakfast with Princesses at auberge de cendrillon (the food was pretty good, but obvs the princesses are the big sell and my two loved it, nearly broke the bank tho!). Try and avoid "standard" kids lunchtimes - see if you can go at 2pm for lunch for example and it is far less frantic!
- Yes take your own snacks and drinks in, almost everything in the park is pricey and unhealthy! also buy autograph books in advance (amazon) as the ones in the park are extortionate - for the shops, we made it v clear from the beginning that we would visit one shop at the end of the holiday and they could each choose one gift - was good to sort that out from the get-go...
- Because we all wanted to see the fireworks, we kept our kids up late - bed around 10pm, awake around 9am, but do whatever works for you - beware, you will work miles (my phone said we'd done ~15km everyday!), so everyone does get very tired and need a good sleep! amazingly my 5.5 yr old managed all the walking, 3.5 yr old needed a fair few shoulder rides though, so think about whether you need a pram/carrier/strong shoulders
- we stayed at sequoia lodge and found the rooms to be average, didn't bother with breakfast, but the proximity to the park and advantage of magic hours was ace. its 5mins walk to park entrance, but be prepared to queue as they do bag checks/x-rays...
- there's a TON of info on [www.tripadvisor.co.uk
] - but be prepared to spend several hours sifting through stuff!
have an amazing time, i am sure you will!
