Just stayed here for two nights. As many have said the property is well maintained. Breakfast as gold was in the cafe restaurant on the lower level. As gold this was a decent buffet and even for cash $18 per person would have been reasonable value given the overall quality.
No upgrade but apparentlh the resort was fully booked (and nothing available to book on Hilton app) although it still seemed fairly quiet.
However, we had one major gripe. The website indicates the pool is open from 7am-10pm weather and season depending. When we were there in July it closed at 8. Clearly this should be peak season so should be open longer than it was. On the first night there were a few people in the pool at this time, but on the second there were about 30-40 people who were turned out at 8pm. I did mention this on check out and they seemed fairly non-pleased about it and the lack of information. Expecting to be able to have a pool available until a reasonable hour is, in my opinion, essential in a resort hotel.
