Yes and No.
That's exactly what you get in Portsmouth, which is about a 5 minute drive from the Wentworth. (Perhaps they have a shuttle? ) You won't be walking to a lot of places from the Wentworth. You could stay right downtown Portsmouth, say at the Sheraton Harborside, but that's not a "resort" or the caliber of The Wentworth.

I've never been there, but know some people who loved the Balsams in northern NH.
