Is this going to be a big-city property?

If so, you'll probably find service levels far superior to what you're used to in the past. Make good use of the concierge if you need it. The gym/spa facilities are probably better than at a Marriott so head down if you have the time.

Beyond that, you can always call down for extra toiletries if you want some keepsakes.

But, really: just enjoy yourself!!
