You forgot to mention sleep in there, Serika.
But I do agree and see your point.
However, talking to a 5' petite 22 year old girl wearing a yukata over her Yuna costume and walking between the two hotels alone, I'd rather not do it if I can avoid it. Even with the yukata painted on my back, or in casual dress in baggy clothes to make myself look more unappealing, I have a target painted on my back that I'd like to erase. That won't happen unless I can carry a metal base ball bat that I can swing at will at anyone who comes up to me looking like they're going to harm me, which would cause a million issues with the Weapon's Policy.
What I mean is, if the Hilton can spare staff to let us into the Park and Go at any time during the night while the convention is going on, I'm sure the Con Staff can let someone outside to walk with someone from one hotel to another. Yes, while most people will want men since they're an automatic detraction, it is always safer to walk with at least one other person. I rather would be traveling in groups of 3 or more, but that's because I'm paranoid.
Also, no matter how "safe" some area is, for someone who does not live in the area, has past circumstances, or is walking alone, or is in general feeling unsafe walking between two hotels, they have the right to ask for an escort. We could ask the Vancouver police to see if they'd be willing to patrol the area, one around the Red Lion side of the bridge, and one closer to the Hilton's garage, since they are already looking after the park.
