We *might* be going back to Disney next year. We have only gone during un-busy times before. I'm guessing that we'd go as early in June as we could go. DD gets out of school on June 1st next year. It will be busier than we've ever seen in (we've gone in late January and late April before when crowd levels were between 1 and 4 each day) but the least busy we'll be able to do for the foreseeable future.
We're not early morning people. There's no way we're getting there at rope drop. We're not morning people and the hour time change makes it even more impossible for us to be early risers! All that to say, we're sort of leisurely WDW-tourers and we're ok with that. (I'd rather add an extra day(s) than try to cram as many things as possible into each day.)
I'd like to see about going to Universal, too, and seeing the Harry Potter stuff. I'm not sure how much time to allow for WDW and for Universal and how to split the time. I know we'll stay on WDW property. I'm not sure where we'd stay when visiting Universal.
If you've done a combo trip, how much time did you spend in each place? Or if you're really good with planning, what would you recommend?!
