Hmm, that depends.

There’s some hiking you can do around there, there’s the hot springs themselves. You could spend some time in the living room at the inn reading, playing games etc. I think there’s a small boat you can boot around in. You might want to check and see if he’s got kayaking or somesuch hooked up by now.

If you like to have a fair amount of variety in your activities from day to day you might get bored.

My personally, I’d love to stay there for a couple of days and go to the hot springs each day, and then just sit at the innchanter and read/sleep/play games, etc.
