Been there once. It had only recently opened, and they did do us a favour with the "quarantine" thing that only got rescinded here last year. (Last May. -They were an approved 'quarantine' hotel).
Food was okay, but the service was poor, tbh. Hopefully, they may have sorted that out by now.
If it's a "rooftop" setting, I'd rather to to the "Kameo" hotel in Rayong. The "California Steak" restaurant there is pretty good. Food, service, and price-wise.
