yes, the Me hotel... formerly the Melia Turquesa or something like that. just reopened, supposedly pretty fancy.
haven't you looked at a map of the hotel zone yet? here's the deal.... on the map, Cancun is shaped like a '7'. click here for map: http://www.advantagemexico.com/cancun/images/cancun_zone.pdf at the top left of the '7' is downtown Cancun. that is Km 0, and as you move along the top of the 7 toward the party center the Km markers will increase (inside yellow circles). Punta Cancun/party zone area is at Km 9. Me, or Melia Turquesa, is at 12 actually, you are at 13. So not a long walk at all.
