Cancun-Hotels.org

Over 7 million google results, gets about 250,000 searches a month (according to the adwords tool), PPC bids are at around $2.25. Taken in com, net, info, biz, mobi, ws, us, cc, co.uk, eu. Archive.org results from 2001, when it was a developed Cancun travel site.

Obviously the dash hurts the value somewhat, but Google doesn't differentiate for SEO purposes, so the potential to rank highly with this domain is huge (of course with a nicely developed site on it).
