We went to Florida in July of this year and really did not enjoy it.
The last time I went was in 1992 when I was expecting my first born and we didn't do any of the Disney Parks, mostly had a beach holiday at Treasure Island and Fort Lauderdale.
We booked to go again this year now my children are 8 and 4 and, once again, I was pregnant - planned but happened sooner than expected.
When we "did" Orlando, we stayed in Kissimee - a short drive from the main parks in Orlando but a lot cheaper than International Drive.
I have to say though that I wouldn't go again. Ever since my children were born, we have always had what I would call a typical "beach holiday", i.e. hotel on beach in Spain/Greece, etc. Both of my children are "water babies" and love swimming and when we "did Disney" it was so hot and humid and the crowds were unbelievable. They have something called "Fast Pass" where you can get a ride time but you can only use the "Fast Pass" once and then have to wait until it has expired before you use it for another ride. This sounds okay in theory, but in practice we used our "Fast Pass" at mid-day and got a ride time of 4:10. We then couldn't use the Fast Pass again until we had ridden the previous ride at 4:10.
As I said, the queues were unbelievable - because of the age gap between my two, what my eldest wanted to go on, the youngest couldn't because of height restrictions and what the youngest wanted to go on, the eldest didn't want to because they were "too mild".
We actually left Disney at about 3 pm in the afternoon and didn't bother staying for the Main Parade or the fireworks.
All my children were interested in was getting back to the hotel to go swimming.
After doing Sea World (which they thought was a lot more fun than Disney) we hit the beaches at Treasure Island (St. Petersburg) and they seemed to enjoy their time there a lot more than the Orlando Theme Parks.
This is just my view - I know other people who have been and think it is just wonderful. Everyone has their own opinions and your kids might just find it as magical as it is supposed to be.
