I've been to Las Vegas countless times. I recently found an odd thing when trying to book my next trip; We are traveling with another couple this time. This couple is, let's say, frugal, so my wife and I decided we would get a room, two double beds, to save a little cash. I have found while booking online, that you can book the exact same room, two queen beds, and the price difference is up to $200 difference, depending if you say 2 people are staying or 4 people are staying in the room. I'm sure someone here has done what I plan to do: The two boys check in. Then later bring the two ladies up to the room with their luggage. The hotel can't check that right? The only way they would know would be the maid would notice too much luggage in the room. Normally I wouldn't care, but the price difference it quite large. Any comments?
