We are flying into Cancun next July and will stay for one night before starting a tour early the next morning. We'll arrive 9am so will have a nice chunk of the day to see the beach and waters of Cancun. I've seen mention of the "7" shape of the beach hotels - which part of the 7 would have nicest beach and water views? For example, does a particular area have prettier sand and/or clearer, bluer water? It's only 1 day but I'd still like for us to enjoy a nice, relaxing beach view before embarking on our tour. Thanks for your responses!
