Hotels. I ran a quick check on TripAdvisor to see rates for those near (walking distance) to the location. It gave the following results, but YMMV. Not making any specific suggestions, you can research that yourself.

148 Grand Jersey
118 Savoy
116 Radissson
115 Royal Jersey (BestWestern)
110 Hampshire
109 Norfolk Lodge

I suggest avoiding the Pomme d'Or (150) and the Royal Yacht (145), as that's in a "Clubbing Area" and may be rather noisy. Both are nice enough places, but not necessarily on a Saturday night.
