Our hours are always the same:
Marketplace
Sunday - Thursday 9:30am to 11pm
Friday-Saturday 9:30am to 11:30pm
The West side opens a little later and stays open a little later, but I don't have the exact hours handy. I don't think the shops at PI open until about 4pm or so, but they probably stay open pretty late - later than we do.
