Largest hotel

We need to do some research here. What defines the largest hotel? The number of rooms in one building, the MGM Grand Las Vegas with 5,044? The number of rooms in two buildings First World Hotel? Or the total number of rooms available, the MGM Grand with 6,852? Or do we only count rooms with toilet and bathing facilities in the room? Vegaswikian 05:18, 28 November 2006 (UTC)

* Vegaswikian, I think you should go ahead and list the MGM Grand as the largest, since it's clear that other large hotels (including the First World, and the Ambassador City Jomtien) are complexes with multiple buildings. I'd say it's not the number of physical buildings (after all, many, many hotels, such as resort lodges and motor hotels/motels are made up of smaller buildings) but the fact that the whole thing is operated and managed as a single unit. --MCB 23:08, 5 December 2006.
o Does the fact that the MGM additions include condo hotel rooms and suites reserved for high rollers (not rentable) change your decision? I still have a concern that while all of the MGM is operated under one name, there are various check in places since the complex is so large. I'm just asking about these so that we are clear on the criteria being used here. I have no problem making the change. Also, 576 of the condo hotel rooms will be opening this month, so waiting till then before making the actual article change might be wise. Also should there be a timeline list of largest hotels?

MGM Grand's article here in wikipedia says it is the 2nd largest in the US behind the Venetian and no where is the 6,000+ number used about one building or the complex.... I'm confused....24.182.142.254 (talk) 04:56, 14 November 2008.
