Too time-crunched for an 80- minute massage? JW Marriott’s new Spa by JW recently launched express treatments at the Houston downtown property and will roll them out at more than 20 of the company’s hotels by year’s end. Guests can book podlike suites on the fly for 12- to 25-minute energy-boosting back rubs and muscle-relieving body treatments. The key innovation: amped-up massage chairs with built-in heating, aromatherapy, and plenty of outlets (so your gadgets can recharge while you do the same).
