Klosters, Switzerland

Okay, the fact Prince Charles comes here every winter with his family is the only reason I'm writing about Klosters. It's a half dozen miles down the mountain from the better known ski resort of Davos. Actually, Kloster is an upscale, compact little community. Not much as far as commercial activity but there's a village feel to the place. Yep, it's big with the English and even boasts a nine-hole golf course.

Is this place hopping or is it dead in the summer?
Nice mix of locals and visitors.

Is there a lake and/or golf course in town?
There's a lake at the edge of town and a golf course on a plateau above Klosters.

Arriving by car the only option?
The train stops here on the way up to Davos.

Does the place feel claustrophobic?
It could.

Lots of choices for acccomodations (hotels/ chalets) and do I have recommendations?
At least seven **** star hotels.

Could I spend a whole summer here or would I get bored?
No, 10 days would be the limit.
