I noticed something weird when I went to visit Bailey's hotel Hotel Regent Adelaide.
He appears to have visited his hotel 4 times in 1 day.
Surely this is some kind of glitch.

Surely this is some kind of bug??

i can answer that, and hopefully be backed up by some others, when i change my ip address for reasons of hydra visits etc, i can then visit again, but then i cannot visit for 24 hours, usually when i do this(and i am not the only one who does) i then visit others, but can only visit in 1-2* rooms, and they haven't been visiting me back, so i visited myself this time.

its not something i abuse, as i can change my ip up to 100 times a day for visits, and yet i do not do this

and i have visited you multiple times as well.. hehe

It's all good. Was curious really (and a little jealous).
I guess that well and truly answers my question - its done by IP and not user name.

yes by ip, you log out and get the popup of visit this hotel, and then you log in and it registers to the user
if i didnt log in then it would annonymous, as you would see on a couple of hotels around when you see a bunch of annonymous visitors in royal suites, similar, not exactly the same though
