Thanks @
Cledaybuck. I actually laughed out loud at the cabana prices when I saw them - it sounds like going with chairs will be ok.
Also, any idea if it is realistic to make a drink up in the room (in an enclosed container like a Yeti mug) and bring it down to the pool and/or beach? I've done this at other resorts without issues, but figured it's worth asking. I'd just prefer not to pay for $12 drinks when I can make a Vodka Soda for ~$1.
