Considering Disney World for Honeymoon, first timers

May stay 2-3 weeks

I certainly wouldn't spend 2-3 weeks at Disney. And would wait until the heat
subsides. Go in January or Feb. Lots to see and do all over Florida, depending
on your likes and dislikes. Personally,IMHO for a honeymoon, an Inn in Key West
for a few days would be delightful.
