Hi
What at lovely reason for the trip (not that dibbers ever need a reason to visit Disney!).

I'm no expert but, have seen rs transport get several mentions and good reviews on here.

As for tickets, people recommend 365tickets, piqnic (not quite sure of that spelling, but it's not normal picnic) and Attraction Tickets Direct. Offers pop up from time to time. There have been a few ticket threads lately, so it might be worth reading through some of these for extra tips.
