What can I say about Lido Palms? Mostly that I wish I were still there, or at least that I lived closer so I could go back sooner. I chose Lido as home base for my CA desert road trip after reading through TripAdvisor reviews, and I could not have been happier! Lido is small (11 rooms), laid back, and friendly, and the main feature - the waters - are heavenly! The largest pool is about 90 degrees, and I spent most of my time at Lido floating on my back in it. There are also two hot tubs ... one outdoors and one indoors ... that are roomy and very relaxing. The mineral water itself if fantastic ... it softened my skin and brought great relief to my many aches and pains in the four short days I was there. As a plus, Desert Hot Springs taps flow with this same fabulous mineral water (which is apparently award-winning), so you have no excuse not to keep hydrated while lounging poolside!
Lido is within a 5-10 minute drive from restaurants, supermarkets, etc. in Desert Hot Springs and only about 15-20 minutes from all the shops, sites, and activities in Palm Springs. (I recommend the Aerial Tramway ... stunning views!) It's also only 40 minutes to Joshua Tree National Park, which is not to be missed. On the other hand, maybe you just want to hang out in or near the pools all day ... it was a tough decision for me each morning!
In-room massage is available at Lido ... ask in the office. I had deep tissue, and it was great. Martin, Lido's manager, is very friendly and helpful, by the way. He freely offered to let me stay past check-out on my final day, since they didn't need my room that night. Needless to say, I took him up on that without being asked twice.
My only regret about Lido is that I didn't stay longer. I tried to cancel the last leg of my trip - 2 days in LA - to extend my Lido retreat, but the other hotel wouldn't let me off without paying. Alas. My advice is go to Lido Palms, and stay as long as you can. (I'm hoping to return with my mother next year, since I think the waters will help her arthritis.)
