Las Vegas has a massive hotel inventory: estimates for the region put the total at around 150,000 rooms, while the Las Vegas Strip accounts for roughly 85,000–86,000 (these figures can shift due to renovations, closures, and changes in room counts). Within that landscape, Treasure Island TI Las Vegas is a strong example of scale, with 2,884 rooms and suites.
And since many travelers visit in groups, it’s worth noting: when you need to sleep more people in one room, a “third bed” is typically handled as two beds (e.g., two queens) plus a rollaway/extra bed (when available), or by booking a larger-capacity suite. At Treasure Island TI Las Vegas, the best approach is to confirm bed configurations during booking and, if needed, request an extra bed or crib based on availability.
