Mate, if you sit at the Hooters down below, you are basically opposite the back entrance to Thermae.
The taxis with the PLT's all pull up outside.....
It's a wonderful hotel, modern, clean and top notch service. never a problem with girls and as someone has already mentioned, the back entrance is a bonus for access to T21 / Cowboy etc.
(my first ever barfine from Tilac actually showed me the way) lol
