Paid $20 for just and umbrella (way too overpriced in my opinion) then about 2 hrs later some guy started to close all the umbrellas including ours due to safety reasons???...I asked him to explain or provide details but he kept walking saying there is no refund....if you dont want to be robbed or rhave your day ruined at the beach stay away from them.
