I have an Alamo membership, and have two reservations which are currently active, both for the same dates. One is a "safe' reservation, and the other one is a little risky. It has codes I've entered which I can't produce a coupon for. I was wondering if anybody knows if there is any harm in keeping both reservations, and trying to use the one for the lower rate (about $125 for a week), and if that fails, I could go with the other one, which is closer to $150 for the week. I plan to use the kiosk, which I know is generally safer, but still feel like I'd like to have a back-up plan in case it fails. My question is this. Is there any problem. since they have no credit card info in advance, in keeping both these reservations just in case the better one should be turned down, or would the safer route be to just go with the "safe" reservation, and pay the extra 25 bucks. Thanks in advance for anybody who has any ideas, or has tried this before.
