A hot tub with wine and appetizers Friday night in the hotel
A short, relaxing, non-rushed hike to the hotsprings in the hills behind the hotel where you loll around all afternoon with your hotel supplied lunch and wine.
The jacuzzi with wine and chocolate after dinner back at the hotel.
Sunday at the spa with warm towels on your face and body after a hot oil massage, with, of course, wine and snacks.
Monday morning breakfast in the glass-enclosed dining area off your suite, followed by quick dip in the jacuzzi or hot tub before packing up to go home.
Sorry -- I'm not much of a traveller, but we also would need to know where you are originating from to take into account travel time. I only know you're in the US somewhere.
