You get one TS meal credit per person, per night of your stay but you can use them all in 2 or 3 days or whatever days you want to if you want or space them out. Just know that if you use 2 in one day, you might run out sooner that's all. They are good till Midnight of your last day.
Each time you use them, they will deduct that amount off your room key. Your receipt will show you what you have left.
Just be careful what you are planning. I don't know if you were just using an example, but Planet Hollywood is not available on the DDP, as far as I remember.
I do believe you get a coupon for it with your package though.
