Really enjoyed your TR and pics. I've stayed at the Park Royal as well and found it a very nice hotel in a great location. I'd also recommend the Park Royal. It also seems you didn't have any problems trying to sneak girls in because they were at your hotel and in a hot tub !
Regardless, the one night I did bring a girl back, I had no problems. I was in the second building without the main lobby and I never encountered any security. I just walked right up the drive way and into the building. I was rather shocked at how lax the security was.
We got our asses waaaaaay drunk.... Good to see you made it back alive, sir! Excellent partying with you and your buddy. We shall do it again soon on home soil
