That beach looks great, Sandi!
Sharon's birthday is in September, but we'd probably be taking the trip some other time. I don't think I want to go during spring break, so it will likely be in December.
I've no clue yet about what the Caribbean weather, and Cancun's specifically, might be during that time of year and what the high and low seasons are there.
I've been poking around some of the all-inclusives to see what they might offer. I'm thinking they might work out to be a better value overall....
