Betty, this sounds more like it can be used with an on-line purchase but ours really isn't....they want a photo copy of the front and back of card.
Maybe I'm being paranoid....watch too many crime shows on TV! One good thing is that our passports don't have address, zip, or s.s. #.

Don, we're not talking about a lot of $...$70 per person includes round trip to/from airport and a 5 hour tour (including admittance to park). If for any reason we had to cancel, it wouldn't be the end of the world.

Maybe Maria is right...maybe don't even need a guide!
