My wife and I were in Green Bay for a friend's bachelorette party. The price was right, and from the description and pics, the Mariner seemed like an okay place for our needs - just a place to crash for the night.
First impressions of the hotel were not great. Walked into the rather dark lobby to check in, and no one was around. Rang bells, looked around, couldn't find anyone. Finally, after waiting a while, a somewhat disheveled-looking and odd inn-keeper came out, checked us in, and led us to the room.
In the hallway on the way to the room, an old stove was sitting in a nook, not plugged in. I didn't care too much, but it certainly didn't give the impression of a tidy, well-kept place. The room door was still on a key system rather than cards, and the inn-keeper informed us that the toilet water supply needed to be turned off between flushes.
The room itself was a little musty, but alright. Mattresses were really old. Sort of like a Days Inn room circa 1985 that had never been updated. But relatively in order.
Well, we got back from festivities that night around midnight. No one at the front desk, which kind of weirded us out, given the lack of other security. Then as I was unlocking the door, a girl poked her head out of her door down the hall, looking like she was anticipating something. We said hi and went on into our room. Couple minutes later, she knocked on the door asking if she could use the phone because hers wasn't working and there was no one at the front desk to make that phone work. It was a little unsettling, but she knew we were awake and given that hotel, it was a believable story. We let her use the phone for a couple minutes. Seemed like an ordinary enough conversation, telling someone she was at the Mariner (didn't mention our room number). Then she left.
An hour or so later, as my wife and I were falling asleep, there's banging on our door. Someone looking for someone else. Freaks us the hell out. We hunker down and silently call the front desk. No answer of course. Try again later with the same result. Then a half hour later, more knocking on the door. Then our phone rings. Then again. At this point, it's well after 2am.
We went over our options and figured we were safer in the room than elsewhere. So we unplugged the phone and I caught a couple hours of sleep. My wife couldn't sleep at all. We packed up early and left once there was full daylight. And of course, no one at the front desk when we left.
I don't know what kind of shady activities were going on in the hotel that night, but I strongly recommend avoiding this place unless you absolutely have no other option.
