First Negative RevPAR Week Since April, and Las Vegas Fell a Third

CoStar / STR weekly data via Lodging Magazine, Sept 17, 2026; Skift Daily Lodging Report, Sept 16–17, 2026; Hotel Dive, Sept 17, 2026 — Tag: Hospitality / Operations / Market Data

Key Highlights

• U.S. week ending Sept 12 (CoStar/STR): occupancy 62.3% (−4.6%), ADR $160.57 (−1.7%), RevPAR $100.08 (−6.2%) — ending 21 consecutive weeks of year-over-year growth.
• Top-25 markets RevPAR −10.6% vs −2.6% everywhere else; upper upscale −15%; economy +4.6%, the only chain scale to grow.
• Las Vegas ADR $149.68 (−20.2%), RevPAR $97.55 (−32.8%); Phoenix RevPAR about −30%; Chicago about −26%; Minneapolis occupancy 57.8% (−17%).
• New York the outlier: occupancy 91.8% (+4.1%), ADR $435.43 (+7.1%), RevPAR $399.60 (+11.5%).
• Calendar: the Labor Day and Rosh Hashanah shift distorts the comparison; the same week also brought Starwood/AJ Capital's Field & Stream Lodge Co. conversions in Bend, Ore. (151 rooms) and Big Bear, Calif. (148 rooms) for 2028, and the 252-room 1 Hotel Austin opening.

The Signal

• The headline is a calendar; the composition is not — economy grew, luxury fell, and Las Vegas lost a third of its RevPAR on rate.
• Weakness concentrates in big-market convention and leisure demand, not in secondary markets.
• New York at 92% occupancy and a $435 rate is running its own cycle.

CoStar/STR's weekly print for Sept 6–12 broke a 21-week growth streak: RevPAR $100.08, down 6.2% year over year. Occupancy fell 4.6% to 62.3% and ADR slipped 1.7%.

The calendar explains part of it — Labor Day landed a week earlier and Rosh Hashanah pulled group demand. Strip that out and the segment mix still tells a story: economy was the only chain scale to grow, up 4.6%, while upper upscale dropped 15%.

At the market level, Las Vegas RevPAR fell 32.8% on a 20.2% ADR decline; Phoenix was down about 30% and Chicago about 26%. The top-25 markets fell 10.6% against a 2.6% decline elsewhere. New York went the other way, up 11.5% on record-level occupancy.

For underwriters, Las Vegas is the number. A 20% rate decline in a market where the 2026 event calendar was supposed to hold pricing is not a holiday artifact, and it lands on top of the softer summer the Strip already reported.

The rest of the week's hospitality tape was constructive. Field & Stream Lodge Co. is buying and converting tired select-service boxes in drive-to recreation towns rather than building; 1 Hotel Austin opened in the city's tallest tower. Brand growth by conversion continues even as top-25 demand softens.

Implications

Owners in Las Vegas and Phoenix: re-run 2027 budgets with ADR flat-to-down, not the +3% default. Lenders: economy and select-service in secondary markets are the segments with positive RevPAR; luxury and upper-upscale in the largest markets is where 2016–19 underwriting is most exposed. Developers: conversion is the growth channel — the capital that is expanding brands this month is buying boxes, not breaking ground.

One bad week is a calendar; Las Vegas down a third on rate is a market.
