I haven't been but it's got a website seahorsebeachclub.com. Your hotel has prob got an agreement with them but you can also get free shuttles to the other private beaches like Sugar beach (those two are the biggest with camping facilities too) and Joseph's etc.

My advice is give them a try and do the lagoon as well!

The beaches in the lagoon only have pedaloes as motor boats are not allowed into the area.

Yes the beach is sandy, still a few sharp stones getting in or out of the sea but mostly sand. There is a beach bar and also a very nice restaurant perched up on the hill where you can get a good lunch and has very please views with cooling breeze.

Well worth going to as is Sugar Beach jusy down the road

yes seahourse beach is suarah beach i believe
