We are going to Disney the first week of June. I had planned to make MGM our first stop on Monday, but I noticed that on Mondays they have extra morning hours and we are not staying on site so we won't get in early. I had read in some posts to avoid parks when they have extra hours because the crowds will be bigger. Do you think this will be a factor this time of year? I would like to sidestep the extra busy times if possible. Thanks for all your wonderful experience.
