We are not worried about weather so much, as time. My husband is running the Dopey that weekend and we are going to the 8:30 show the evening after he finishes the marathon. We did that a few years ago and he rested afterwards then we took a taxi to the show. It was nice for him to get out and celebrate, and didn't involve a lot of walking on his tired legs! There were no mini vans at that time and we had to take a taxi to the main area then a shuttle. This year my parents and 17 year old daughter are joining us, so we will probably all be a MK and he will take a mini van and just meet us at the show. I wanted to know if the mini vans were allowed to go all the way to the show because that definitely makes it easier for him that evening.
Thanks everyone for letting me know that I was correct in believing they could straight back to the show. This will definitely make the evening easier and more enjoyable for him!
