Wow, I will have to savor this thread and read more slowly, but thought I would add some interesting rooms/suites here, in no particular order (no, they do not hold a candle to some of the suites described in this thread):
1. Lizard Island, Australia - Sunset Point Villa
no keys, no locks - we left the sliding glass doors open all day and night while we were off exploring the island. Views from the bed out to the sea; daily 4pm delivery of ice and cookies. The pictures on the website really don't do it justice.
2. Bora Bora, Pearl Beach - Deep Overwater Bungalow
Again, a magical experience. Your own thatch roof hut with no other huts visible. On its own private motu (island), Views across the lagoon of the big mountain on Bora Bora. Clear glass coffee tables and end tables, as well as counters in the bathroom, so you can watch the fish, octopi, skates and rays swim by. Private bi-level deck to the lagoon with its own outside shower. Turndown service included flowers on the bed. Again, I don't think we closed the sliding glass doors ever. Even with a water shortage on our last 2 days, I almost cried when it was time to go.
3. San Francisco - The Palace Hotel
Was a repeat visitor for business in years past, and got complimentary upgrades several times. The craziest one was a corner suite over 1500 square feet with views of the Transamerica Pyramid, a chandelier in the living room, a fireplace, a king sized bed with draperies and a bathroom that had 9 towels of each size in it - with a separate dressing area, sink area, bath area, closet area, and toilet area. The service there is excellent.
4. Aspen - St. Regis
Got a superior 1-BR suite via a luxury link package at the height of ski season for essentially the price of a regular room. This suite was probably "only" 1100-1200 square feet.
Mountainview, 2 full baths, breakfast everyday, fresh flowers in our room. When they saw that we'd brought our dog, Boo got his own bed (a purple and gold embroidered pillow that was so nice he thought it was human furniture, and stayed off of it!), dishes and a place mat. Staff couldn't be nicer. The master bath had his-hers closets, a separate dressing area, and 2 marble wings - 1 side had the toilet and shower, the other had the double sinks and a deep soaking tub. Another nice touch: a humidifier in the bedroom that was refilled every day since the air was so dry.
5. Not really a hotel room but an Experience: The Sea Cloud - a 4-masted sailing ship that was a wedding present from EF Hutton to Marjorie Meriweather Post. Abercrombie and Kent charters trips - the food is top notch, the service impeccable, and the ship is just a dream. Any cabin on the main deck, 1-10, is to die for, kept with same decor as it was in the 30's, but cabins 1 (hers) and 2 (his) are really over the top. (Not to be confused with Sea Cloud II.)
6. Sydney, Australia - W Pier Loft
Again, got with points, got upgraded, so it feels especially luxurious! Bi level loft on a pier in Woolloomoolloo. Neat architecture - it's a converted warehouse/factory on a pier, so all you see out the room is water! upper level is bedroom, open to below, with a small bathroom. Skylights over bed. Lower level is cathedral ceiling living room, smallish dining area (seats 4) and another bath.
