We are on the island now and have been to Orient a couple of times. We grabbed chairs at Chez Leandra, as we wished to support the smaller establishments. We walked up the beaches several times and the Club O section was packed. I didn't see any spare chairs, and in fact, it was so busy that we wouldn't have felt comfortable there (in light of COVID) even being outside. If you're looking for people, the density was much, much higher than any other section of Orient Beach.
