Just observing and guessing. Cedric has his setup of yellow (with s couple of blue) umbrellas toward the middle-to-north end of the CO beach; there are about 10-15 grey umbrellas where Cedric's end, right near Pedro's. They look like nice chairs - mesh vs. strap style. My guess is those are the ones by Colin. Only problem, at least for us, is that this is right where the taxis drop all the cruise passengers.
