Can I do a Reservation, for the rest.? How much 1 night in the hotel. Do you have a package, including hotel and restaurant? How m7ch?

NellyBeans is correct

You can just drink at the bar if you don't want food. Tonga Room no longer accepts reservations for dinner (for parties of fewer than 10). Guests for dinner will be seated on a first come first serve basis, based on party size.  Registered hotel guests have the ability to make reservations through the Concierge or Front Desk.

You would need to contact the property. This is a community of fellow guests. Nobody from the hotel works this forum to answer specific questions like that. Best of luck and happy travels!!
