We stayed one night this September during off-season. I was suprises there are no free upgrades for Hilton Diamond members, you want an upgrade get out your wallet. I was only a $30 upgrade charge but you would think they would comp me. I must admit the one bedroom with kitchen and full size living and dinning room were well worth the $30.00 "and thats off-season cost".
I'm not a big fan of the Time share pitch and you will get it here. The hotel has no restaurant but, there are many within a few minute walk.
