A very important item (as just driving to Ai Ais is a long way from your last tank up), is the fuel station with diesel, and leaded fuel available, also they have a tryre repair service, it is a simple manual tyre repair service so people with expensive aluminium rims beware!
There is a pleasant restaurant with an indoor aircon section and an outdoor patio area, which spills onto the bar area. Food selection is limited but normally cooked very well. open for breakfast (buffet style with fresh cooked eggs), lunch (mostly toasted sandwiches) and evening meals, small menu and items do run out.
The hot springs are available to everone staying at the resort as is the warm water outdoor pool, there is also a spa service offering massages, hair and nail treatments - you need to make an appointment the previous day for the spa treatments.
