We were just at Arashi every day for 17 days as my hubby said. They do rent chairs but not palapas. We would get there before 9 to get one, well our favorite one but there were usually stray ones. As far as vendors, never ever saw one on Arashi beach. Now I will say there was the guy who sold ice cream come every day at 3 o'clock but that was in the parking lot. But never in the last six years coming to Aruba and going to Arashi have I seen a vendor on the beach.. And I must say, thank you because I love to shop. It would not be a good idea for me to sit there and have them come to me with trinkets or anything, lol, lol, lol. The beach is my "safe zone" from shopping, lol.
