University of Delaware Summer Program - how does "Stuff" work?

[Abbyar]

Dd is signed up to 1 week of UDel's summer program - we live close so I'll be taking her instead of putting her in the dorms. Can anyone give me some basic guidance as to what are general operating rules? I've contacted an instructor recommended by her coach and have aligned on coaching times, but don't want to embarrass her or myself by not coming adequately prepared - I'd like to know rules for simple things - as in, is it ok for her to have a snack between sessions? Do I need to show up the evening before to register? Would like guidance from anyone who has attended in the past. Thanks!
