OK...I'll cut to the chase......I have a VIP room key from a previous stay a couple months ago. Can I reuse the key on a subsequent visit? That is, are there any perks of having this room key to just 'flash' at certain places at the Bellagio or will they have to scan it each time to verify if I'm a current guest? (VIP Lounge, Buffet Line Pass, Pool use, discounts, etc.) Thanks. PS. Leaving to Vegas tomorrow....please respond ASAP.
