About this converter
First World runs 7,351 rooms in Genting, 499 clear of MGM Grand at 6,852. Mandalay Bay with Delano at 4,766, Luxor at 4,407, Ambassador City Jomtien at 4,210 and Venetian at 4,049 follow. Bellagio at 3,950 for scale, Caesars at 3,793, Palazzo at 3,068 and Wynn at 2,716 close the table. Counts are hotel keys open for sale, not residences or timeshares. Tower counts merge where operators sell jointly, like Mandalay with Delano. That merged rule is noted per row.
How to use it
Pick two hotels and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try First World against Wynn to see the near triple gap. The bars below scale to First World so Wynn looks thin next to it. Switch the unit to thousands for short figures. Ratios are exact divisions of the room totals.
Mandalay Bay at 4,766 ranks above Luxor at 4,407 despite draft table quirks. Bellagio 3,950 is kept for scale as a famous mid size house. Venetian 4,049 counts suites only. Figures follow hotel specs. Renovations close floors, so open keys move by dozens.
