So far all reports correspond with F2 damage, partial or total roof failures, but most walls still standing. Not surprising as the measured winds from Wilma fit right in the middle of the F2 range.

Still looking for comprehensive surge damage reports from the lagoon wall at Cancun. Photos from your link indicate that most structures avoided major structural damage (no more wondering where the floating glass came from though, the Flea Market was a major contributor) but discovery of isolated catastrophic failures are still possible.
