Every hotel takeover is a bit different. First be sure it is a complete takeover and follow whatever rules the organizers publish. There are a variety of ways to approach this. Many will set up everything in their room: drinks, snacks, toys, etc... and keep the door open or just bring friends back to the room. You don't want to carry a lot with you when walking through the hallways, playrooms, dance floor, etc. Condoms and lube in the husband's pocket and carry your cup or bottle if you want. The big thing is to relax, meet a lot of new people, and have fun. Hotel takeovers can bee chaotic for many new people because there is movement everywhere. Find a place you want to relax and be engaging and you should be fine. Also, send messages to people on the guest list ahead of time and it can facilitate fun and take the pressure off a bit for some. Just realize that not everyone on the guest list will show. Have a great time.
