I don't like Aria much for access to the Strip as it takes forever to get anywhere (either a walk through the adjacent Crystals mall or around back onto Harmon). Aria is not actually set back that far from the Strip, it's just that the casino floor is not laid out well and the City Center complex is convoluted.

This is a new one to me, may just be a website glitch (mLife is known for that). ExpressComps are never supposed to go negative since it's a balance account with expenditures controlled by the player. Players can get overcomped on other balances, but they shouldn't on ExpressComps - and they also shouldn't deduct from ExpressComps to cover overcomping elsewhere, otherwise the system is not working like they are telling us it is supposed to. Check with a host and let us know.
