Planet Hollywood ADR for lunch?

[emilyclaire]

I was planning on leaving the last day of our trip "open" so we could use it for whatever we didn't have time for on other days. (It will be Saturday, 10/20). If all goes as planned on the other days, I would like to spend this day in DTD shopping and use our PH voucher for lunch (not dinner, as our flight leaves that night.) Is PH busy enough at lunch time to need an ADR? I'm kind of reluctant to make one since my plans for that day are not set in stone, but I will if I need to (and if I can get one this close to time!)
