Funnily enough I am planning a similar trip the same week. I think the all-inclusive reward is a pretty good deal at the CP. But I havent stayed there yet...

Its important to note that the CP is not in Cabo San Lucas, its in San Jose del Cabo. One report was that its a $35 cab ride each way to CSL from the CP.

I assume you have found the special deal on the Priority Club website, which gives you 5k bonus points(plus a few other goodies) for each reward night you redeem?

There are a couple informative threads about the Crowne Plaza in the Priority Club Hotel Forum.

Good Luck!
