I'm afraid I've only flown in fixed wing on floats.
However this is a reasonably sized single terraced lawn on te loch side of the hotel. It would be reasonably usable in a single. The location is reasonably sheltered by the terrain but the lawn is largely surrounded by trees - but not of great height. Big but is make sure they do not have an enourmous marque on the front lawn - it was there last time over halving the area of the lawn.
Might be worth ringing PLM and seeing if they have better knowledge.
