no sweat then........use the fotl.......limited waiting times.
i once started the day at 1:30 at the parks and started with the mummy then mib, moved up to shrek, T2 then back to the hotel.
had to get ready for hhn that night and get to the stay and scream at 5.
with the fotl you can accoomplish more than you think.
i have never been at the end of june but would assume there would be crowds. it's tourist season then. hopefully you will not be starting your first day at the park on a saturday. they are busy in the summer.
only have been mid june and late august for summer periods .
i prefer feb/mar/early may/late sept/early oct for my holidays
