HotelChatter

Kate Walsh and her man holed up inside their one-bedroom suite with private pool. Hotel reps report that the duo hit up the hotel's Thalasso spa for a Sunset Couple's Massage on the pier.

Meanwhile, Teri Hatcher and her boyfriend swam with dolphins and took a cruise in the resort's 50-foot catamaran, La Bonita. And if you ever wondered how Teri stays so thin, perhaps you could chalk it up to her good metabolism. Apparently, Teri and Stephen dined off the resort's Four Elements restaurant menu inside the freshwater infinity pool and Teri loved Chef Marc Dobbel's guacamole so much she ordered it everyday.

Now that you know some personal details of their vacation habits, we want to know what were they doing there? It turns out the resort was doing some good by hosting a charity event for the Sian Ka'an Biosphere reserve.

On Saturday night, May 26, both stars attended the glitzy anniversary party hosted by Carlos and Elisa Gosselin, owners of the resort, with fireworks; a fashion show by jewelry designers David Yurman, Cartier and Chopard; and a charity auction. Proceeds were donated to the nearby Sian Ka'an Biosphere Reserve, the Yucatan's World Heritage Site, raking in more than $22,000 for green energy.

Man it's good to be a celebrity. Show up for charity event, get massage and eat guacamole and you can say you were helping out the earth! Let's just hope they didn't fly a private plane there. And if they did then we hope they bought some carbon offset passes.

Thanks Tania for the pix!
