Issues as in stuff that just come with staying at a hotel. Especially crowded ones during Fanime. (ex. Elevator Traffic, Roomates having bad hygiene, pooing, etc This is more of a casual community conversation rather than a "complaints" thread.
For me, Elevator Traffic would depend on the hotel. I stayed at the Fairmont my first year and the Marriot for the past two years. For the fairmont, it's generally okay since it's one of the farthest ones from the con. So far, I haven't really had any complaints on waiting. The Marriot, being the closest one is obviously known for the long elevator waits. My general rule of thumb for me and my mates is that we'd use the stairs if it's at least floors 1-6ish. Otherwise, we'd just survive the wait.
Pooing issues. To try to maintain a serious tone may be a general problem depending on how comfortable you are. Usually, to be polite. I'd usually go when people are off strolling around the convention or at night when many people are asleep. But if I have to go real bad, then I would just go.
Marriot Bathrooms. For people who haven't stayed at the Marriot, one of the biggest things that stray people off is the bathrooms. There's no locks on the bathrooms, which when I initially stayed there my first time, I naturally had that suspicious and paranoid vibe. But eventually I got comfortable because my group just trusted each other. We made a pact not to joke around. That it's some sacred area. No jokes, no pranks, nothing eff'd up. We used one of the clothe hangers to signal that it's occupied.
Food. Some people are freeloaders, some people are polite. It's natural with the group. Despite bringing my share for the group, I always tend to have my own secret stash just in case of emergency.
Anyway, that's some of mine. Anything interesting you guys experience in the hotel that you remedy?
