We went two summers ago with four children aged 1- 5. We took the car and went via the Eurotunnel, which was very quick. We stayed at the Davy Crockett Ranch and seven of us stayed in one cabin which was really roomy. You collect breakfast and take it back to your ranch - it's usually baguette, mini croissants, butter, Nutella, hot choc sachets etc.
The restaurant onsite is okay and reasonably priced and there is a pool. I thought it was a really good location to stay. The characters also make appearances and do photo sessions.
We only had three days in the park. It is looking a little tired and shabby in the main park now but is still good fun. The parades and fireworks were lovely. The Buzz Lightyear ride is awesome!
We didn't do any shows due to lack of time and we only visited the newer bit of the park (MGM studios) on our last day. Lots of new rides there and stuff from more recent films. Wish we'd done that bit first.
The food available in the park is crap - expensive fast food unless you go to a sit down restaurant. We ate from the street seller carts who do also sell fruit if you get sick of sweets and ice cream.
Our little twins who were just over a year old went on most rides with us. Queues were not too bad and this was August.
We are not the type of family to have a plan of attack when it comes to theme parks so I can't tell you stuff like 'go here first, do this next etc'. So not many useful top tips really, other than take some food with you. Oh, if you stay in Disney accommodation like we did you get an early pass so you can enter the park before it opens generally. Or, if you arrive at your accommodation in the afternoon, head straight to the park in the early evening. Lots of people leave then and queues are a lot shorter. There are fast track tickets from machines too if you want to jump to the front of long queues. It gives you a time slot to return to the ride.
Some of the rides are still open during the firework display so if you miss them earlier in the day you can catch them when others are watching the display (we did this with the Toy Story ride).
You can hire strollers (not sure if there is a charge) and lots of people did this. They all get parked up at the entrance to the rides.
Umm, can't think of anything else. For us it was a nice, relaxed few days and I think in a week you should have time to do/see lots.
