Flims, Switzerland

Flims isn't too big a place nor is it too small. The valley is nice and wide which is great as I dislike feeling hemmed-in. Nothing special about the main shopping street. Big patches of farmland spread about the town stops willy-nilly growth.

Is this place hopping or is it dead in the summer?
Pretty busy place.

Is there a lake and/or golf course in town?

Arriving by car the only option?
Frequent public bus service from Chur (20 minutes)

Does the place feel claustrophobic?

Lots of choices for acccomodations (hotels/ chalets) and do I have recommendations?
Quite a few hotels to choose from. I spent a night at the five star Waldhaus Flims Mountain Resort & Spa and give it the two thumbs-up.

Could I spend a whole summer here or would I get bored?
Ten days would be the maximum.
