Not rough so much as rocky with off-shore reefs a few feet in. Great for snorkeling before lunch. There's plenty of beach for walking -- I spend my pre-meal time with Nat's unbelievable rum punch! Can't remember about the chairs (blame the rum punch).
We love Palm Grove. We go there a couple of times every year and love spending the day there. My favorite is bbq chicken with johnny cakes and yes, the rum punch is very goooood.
No shade is the only bummer, one little thatched umbrella but you have to get there very early.
6 more weeks before we get there again.
Don't wait 'till you are starving to order, the atmosphere is very casual and relaxed.
