I really don't think that it matters if anyone else is there or not. I used the pool there this summer and found the service second to none - far better than ending up in a noisy brash
hotel anyway. The few guests that were there this summer did seem keen to go back before the end of the season so you may be pleasantly surprised.
Seriously though I'd make the most of it as when word gets out i'm sure this hotel will become very popular!!!
