We went to the pool for three days in a row.
Day 1 - We rented the $150 "cabana" which was actually a short chair for two with an umbrella. When all was said and done with food, drinks and required tax and tip we totaled out at $365.
The services was excellent. The reserved chairs definitely get dedicated and preferential service. I do see now in looking at my bill that I was overcharged for two lunches that someone else must have eaten but it's my bad for not catching it.
We were there early enough that we scored a couple of the in water lounge chairs for a good part of the day. That made a big difference.
This was also a Thursday so the crowd was much smaller
Day 2 - We arrived a little later and decided to sit close to the Bellagio side on two chairs that were a little more secluded.
Even though it was a Friday and it was more crowded the service was still good.
Day 3 - We sat on the Bellagio side but on one of the upper decks.
Couldn't get service. Had to go to the service podium any time we wanted something. In the server's defense, it was very busy and there didn't seem to be enough servers. That said, we left after about 45 minutes because between the lack of service and the heat, it wasn't worth it.
Also, bring music and headphones because the piped in music isn't very good.
The food is typical pool food and is passable for one or two days.
