Well, it's hot HERE in June too but we aren't stuck outside all day walking around on the cement.
The park touring style is MAJORLY different. Not sure what else we could have done. I know that after a couple of days I told DH we needed to slow it down. It was painfully obvious that we would NOT be able to ride everything we wanted this trip. So we may as well just take our time and walk slower and pay attention to all the details we never see in the winter because we are running by them. This trip we missed ToT (DH,not me! I'm not riding that again. LOL), we also missed RnRC, Splash Mountain, BTMRR & Space Mountain. Some of those at MK we could have done if we would have worked the fast pass differently. We should/could have waited in line at Buzz for instance rather than using a fastpass. I will definitely have to rethink our touring plans next time. By the end we started "getting it". We just need to slow down from the start next time.
