Sheri, on all other Radisson cruises I've been on you can cancel....something like 24 hours notice (maybe less notice...not sure of that?) For the snorklers, just in case you don't know the Pacific is much colder than the water you may be use to in the Caribbean.
I've been to Cabo quite a few times and there are other things to do there such as horseback riding and renting ATVs and riding up and down the beach.
