We are spending a few days in Cancun. Epic view and weather has been great.
Here is 180 degree view from the patio. Click for the big effect.
We love going to Maui and have been there several times. We don't like the long flight however. A couple years ago we went to Cabo which was fun but we were not nuts about it.
I think that Cancun has the whitest beaches of anyplace we have been (Cabo didn't have great beaches) there just isn't that much of them. I was talking to the pool guy and he said the resorts used to have about 200m of beach (resort to water). After the hurricane a few years ago they now have about 4 to 20 feet depending where the tide is. Pretty Amazing.
