Reviews of popular guest friendly hotels in Bangkok, Pattaya, Phuket and other cities in Thailand with red light districts. Here you will find a list of no joiner fee hotels in Thailand that allow guests to invite bar girls back to their rooms with no extra charge.
The Citrus Sukhumvit 22 Bangkok is a 4 star hotel I recommend in a quiet location off Sukhumvi road. Yet not far at all from the naughty boy action. From the hotel's location you can walk on Sukhumvit road to Soi Cowboy in about 15 minutes for the closest go go bar entertainment.
Another 15 minutes in the other direction on Sukhumvit and you'll hit the Phrom Phrong section of the city where you'll find the Emporium Mall and a large cluster of oil massage parlors that provide happy endings. Though there are some massage shops near the hotel where a couple of my friends told me you can get a rub and tug too. But it's best to stick with the oil massage parlors I've listed on a map here .
Because the Citrus 22 Hotel is guest friendly you can always order up out call service so you won't have to leave the comforts of the room. So the hotel won't charge a joiner fee for inviting a massage girl as well as a Soi Cowboy bar girl or hookers from Nana .
As of writing a superior room cost around 2300THB ($75USD) united kingdom food per night after a 30% off discount . Taxes included. That price gets you a 31 square meter room and I like the way they make use of the room space which makes the room very comfortable. And there's a 40" LCD television too with a lot of international channels. Other important amenities included are free Wi-Fi internet access and an in room safe. And the hotel has a nice small swimming pool but no gym.
There is also a nice little lounge area too and I saw a few Thai girls sitting there together. From the looks of the tattoos united kingdom food and familiar dress of working girls they might be there to hook. Or maybe they're waiting for customers who are guests of the hotel. But seeing them a few nights in a row makes me think otherwise.
