Desert Southwest — Scottsdale, Palm Springs, Sedona
The US's densest luxury-resort concentration outside Hawaii: golf-and-spa flagships (Scottsdale's Phoenician tier), design-forward Palm Springs, red-rock wellness in Sedona. The season is the whole game — winter is peak and priced like it; summer is 110°F and half price, a legitimate strategy if your trip is spa and pool at dawn.
Hawaii
The benchmark for US beach luxury — Waikiki's historic grandes dames (the Royal Hawaiian's pink stucco has anchored the beach since 1927), Maui and Big Island resort coasts, Lanai's exclusivity tier. Watch inter-island differences in weather and buildout; and the resort-fee layer runs strong here, so total-price math matters most where the rates are already highest.
Mountain West — Aspen, Jackson, Park City, Big Sky
Ski-anchored luxury with two seasons and two price books: winter peak, and a summer alpine season insiders prefer. Mud seasons (late spring, late fall) are the value windows if the property stays open. Book ski weeks a year out; book summer weeks when everyone else is watching beaches.
Southeast coast — Florida, Sea Island tier, Lowcountry
Old-line coastal resorts, golf classics, and the Orlando entertainment-resort category of its own (the universal-adjacent flagships like Portofino Bay compete on access as much as luxury). Hurricane season is a real calendar constraint — check cancellation terms with September in mind.
Las Vegas
A category unto itself: the Wynn/Encore tier delivers genuine five-star hardware at scale economics no destination resort matches — enormous rooms, restaurant depth, service drilled for volume. What it does not sell is seclusion. Judge Vegas properties as what they are and the value is real; judge them as hideaways and nothing on the Strip passes.
Northeast — coastal New England, the Adirondack/Berkshire camps
Short-season coastal properties (the Nantucket tier), converted great camps, and drive-market pricing: demand concentrates in ten summer weekends, so midweek and shoulder dates buy access the weekend rates gatekeep.
