Hi MrsEricBana,
I also love Walt Disney World in Florida and have been five times - we took our boys for the first time when they were 9 and 14, which we thought was a good age for going on most rides together. DS2 was still too small for some rides though, like coasters. We usually went for 2 1/2 weeks as there are 4 Disney Parks, 2 Disney waterparks, 2 Universal Parks, SeaWorld, Kennedy Space Centre, Discovery Cove, two more waterparks outside Disney, and Busch Gardens theme park in Tampa.
Agree that you need to pick your time very carefully to avoid massive crowd levels, and avoid the summer months with very high temps and 100% humidity.
October, November ( not Thanksgiving ) April - May are good times to go. Avoid Spring Break like the Plague! Manic!
We were planning a California trip for this September, but has been postponed until next year. I hope to visit all the Disney parks eventually, including Hong Kong, Shanghai and Tokyo - all very different, but still Disney.
We took our boys to Disneyland Paris ( or EuroDisney as it was originally called ) when it first opened in 1992, and carried on going every summer, and sometimes also in December for Enchanted Christmas. We have either flown or used the direct Disney Eurostar train. We still go regularly and both my sons celebrated their 18th birthdays there, and one 21st.
Now they are adult they want to go with friends or girlfriends, so I go on my own or with DH who still likes going occasionally. I was there a few weeks ago for Christmas season, and have booked again for June. This year is the 20th Anniversary, beginning on 1st April, so new shows and parades are planned.
All the Disney hotels are being redecorated and refurbished, and the main Disneyland Park has been undergoing massive refurbishment for over a year, including repainting the Castle which now looks amazing.
I think that Sleeping Beauty's Castle in DLP is the prettiest one, and it has a dragon underneath.
Guide books are worth reading for general information ( there is now an Unoffiicial Guide for DLP ) but as things change in resort frequently, they can be out of date very quickly. People read guide books and expect things to be there when they arrive, then find they are closed or replaced.
DLP forums can help in that respect, as Destination Experts like myself keep everyone posted with what is going on there, and are always happy to answer questions and help with trip planning. The same plan does not suit everyone, as not all people are the same. Some 3yr olds are braver than some 13 yr olds when it comes to rides!
If you decide to go to Disneyland Paris, we will be very glad to help you on our Disneyland Paris / Marne La Vallee forums on Trip Advisor. The Top Questions lists should help as well. Both forums are linked so posts appear on both.
In my opinion, you are never too old for Disney.

Whichever you choose, have a Magical Time!
