Thanks. I'm not sure if I can change in my bag or not. I got it for backpacking so it's a bit snug to save on weight and space. Doubt I can set an alarm without waking anyone up (it's a double wide trailer, they aren't usually very sound proof). Truth is I won't really know the situation until I get there, but these were some good ideas; and it was nice to hear it laid out by someone else for perspective. When I was thinking about it before I even first posted, taking a backpack into the bathroom with me seemed like a red flag and I don't think I can fit my used diaper in my actual toiletries bag lol. But now it sounds like a sound idea. Before, I was thinking how do I slip a grocery bag in my clothes before I change and how do I get out of the bathroom to hide it without someone seeing or asking what I'm doing (It's a very open layout, so exiting the bathroom you have to walk past the whole house [minus the bedrooms] to the kitchen or outside to the bins) but now I at least have a strategy. Also I find it funny I'm visiting these people in Holland Michigan so like an hour north of you? I just thought it was funny the odds of getting advice from someone so close to where I'm going lol.
