I actually own a gay Hotel/Resort (Spartacvs Bali Hotel) on the tropical Island of Bali, Indonesia. There are no discrimination laws here, so my Hotel is for gay "men only", no women & children admitted and all guys must be over 18 years of age. I offer discretion, comfort & security in a 100% clothing opitional enviroment. The ages of my guests vary from 24 to 68 years old, some coupled, some single, some on business, the rest for pleasure. I am fortunate my Hotel is located only a 5 minute walk to the gay beach of Ganesha (Callego) and a 6 minute drive to the gay bars & venues. For added security for my guests, the property is protected by CCTV and Security guards and located in a very quite area surrounded by multi-million dollar Villas, commonally known as the "Golden Mile". If yourself or other guys would like to ask more questions about gay Resorts/Hotels, please feel free to contact me.
I've been to Vegas on business three times and have always enjoyed it, though sadly I never saw a great deal of gay life there - but I did have a busy schedule, mainly based in the big hotel conference centres.
If you've time, I hope you'll maybe blog a bit about what gay visitors should check out, and what life is like for gay men who live there!
Fort Lauderdale, FL had many gay resorts. My favorite is the Worthington Guest House. It is a great place with down to earth guests and a very social atmosphere.
There are many others that you can 'google' and locate more info.
As for the "Dunes", I don't know anything about it nor anyone who has stayed there. Based on what I've seen online, it looks OK but there are much nicer ones...Elysium, Wyndamar, Grand Resort & Spa, Alcazar, Royal Palms, Villa Venice, etc.
Good luck and let me know if you make it south Florida!
When traveling I always try to book a gay hotel or resort, to stay in a comfortable environment but also to support "pink business'. So I always google for gay places wherever I go. In January I stayed at The Basement in Gran Canaria and liked it a lot. So much I am going back in three days from now for a week and a half! The place is small but has a great staff and friendly environment. Plus it is oppostite the Yumbo shopping center where most of the gay bars are. Be prepared to throw off all your clothes though because nudity or jockstrap is mandatory while on the premises (and fetish clothing on their "sex party" nights). They have a playground where anything goes, under the sun or in the darkrooms. Atmosphere is very friendly and customer minded. Highly recommended. You can also buy a day or week pass to visit and hang around the pool (or "get active") during the day.
In August and September I am going to Provincetown, San Francisco and Seattle (start of a gay group cruise to Alaska). I booked The Ranch guesthouse in P'town (any experiences? Please let me know) and am looking forward to the Alaska cruise.
I have not stayed at the Dunes in Fort Lauderdale, but I have stayed several other place, in order of preference I like The Grand, it has a wonderful spa is located very close to the beach. The Cabanas which is closer to Wilton Manors area is also very nice and convenient to the bar/club/restaurant scene. Several years ago I stayed at the Elysium (nice) and The Windemar, also nice. In Key West, Florida Island House is the best but very expensive during season and you have to make reservations well in advance. I am going to Key West for Tropical Heat and will be staying at the New Orleans House on Flemming St., the reviews are mixed but I don't expect to spend much time in the room. Other gay resorts I like are Inn Exile in Palm Spings, CA. (clothing optional) as are all of the places in Florida. In Puerto Vallarta the Hotel Mecurio is very nice but not clothing optional. In Guerenville (Sonoma Wine Country, California) the Highlands is a rustic resort with cabins, nice pool in the woods and clothing optional. The Russian River Resort is also fun, lots of playfulness and although not officially clothing optional the hot tub area is pretty much clothes free. In Maspalomas Gran Canaria I stayed at Tucan's Beach Boys the last two years, very nice except that the WI-FI didn't work last year which caused me a problem connecting with my office. This year I am considering Macha when I go in November. Hope this helps, feel free to hit me up if you have other travel related questions.
