Attending Wishes Dessert Party with a Guest in a Wheelchair

[AlabamaBound]

So, I decided to multi-task while I'm on hold with hotel reservations . I would like to book the Wishes Dessert party, but two things are making me hesitate. First, my fiance is a full time wheelchair user. Based on some of the pictures I've seen of the viewing area, he wouldn't have an issue watching the show provided he is right near the railing. However, I realize that everyone will be looking for the perfect viewing location, and I'm just wondering how "pushy" people tend to be when looking for that spot (i.e. do people tend to rush to the railing and be "territorial" about their space? And is there a limited amount of good viewing space?).

It's not that we're looking for anyone to give up their spot or anything because I realize that everyone is paying for the view in addition to the desserts. It's just that I cannot justify spending nearly $60 on dessert for 2 people if there is a good chance that he will not be able to see the show clearly and easily.

Also, when I went to book it, it said that we have to pay in full at time of booking. I'm just wondering what the policy is if they cancel the dessert party based on poor weather? Would we get our money back without issue, or is it more a "sorry about your luck" type thing if it gets cancelled?

Thank you in advance for your help!
