I have always wanted to go to Vegas WITHOUT already having my hotel rooms reserved and then seeing what kind of deal (if any) I could find. I have never done it because I would end up spending much of my first day, lugging bags around and calling around for rates. I have also been worried about getting robbed on the rates. Has anyone done this? Was it a good idea or did it suck? Well I came across this app for my ipad called "Hotel Tonight" and after 12 noon, it gives you rates for that night of hotels in major cities. The rates look very good, but seems like it only works with a limited number of hotels in Vegas. Tonight's (Thursday) rates given were: Hard rock $49 Paris $49 Rio $28 South Point $35 Palace Station $18 Sante Fe Station $26 Has anyone ever booked using this app?
