A BB Polar Patio in April 2018 is $362.10 including tax. I ‘think’ TL cabana (Beachcomber Shack) rates are the same but not 100% sure. Also I’m not sure if that’s a consistent price all year or if it changes seasonally. Resort cabana rates change seasonally but I’m not sure about the water parks.
It must vary day to day based on expected crowd. I have one booked at BB (23rd) and one booked at TL (20th) for this April, and I paid $239.99 for both days.
