You cannot have party in a guest room or suite of any Good Hotel. Why dont you book a small banquet hall or a bigger board room which are meant for these purposes. Booking a room does not mean that you own the place. It all depends on the noise that comes out of the room and how other rooms near the room react.
What can you do at a hotel party?
You can have games like,Wii, watch movies, dance to music, play flash light tag, tell scary stories,and play games according to your theme, and traditional party games. Get to the hotel at the check-in time on the day of the party.
