Sounds like an easy enough question. I am heading to Vegas for a conference in OCT and have Paris (where the conference is) booked for $119 a night, some 500$ total. I now see the offer for bally's 5 nights deal for $200 through facebook. I have never stayed at either property and was wondering how much trouble it is to get to Paris from Bally's (I know they are right next to each other). I plan on peeling myself out of bed with minimal hours of sleep (if any), and I am wondering if being on-site instead of next door is worth the extra $300?
