Last year we went Spring Break and couple weeks before, they changed MK and other park hours to an hour earlier opening nearly every day. If we are going last week of June, is that likely to happen again? I got a pre-RD BOG and wondering if that will turn into a during-early-opening bfast, which is less desirable.
The last week of June is a great week to tour. The only change may be a change in EMH (sometimes they change the days) but you should you that ahead of time. I would book an extra pre Rad BOG or other breakfast if you are worried. In June 2014 when I was in the world the crowds were much, much lower than predicted. It was wonderful!
