When I was using the PD cycler, I ended up travelling overnight by myself and was not able to lift the machine on my own. I went into the hotel lobby (it was a small place with only one staff member on duty), and found a family and asked the wife if I could "borrow" her husband for a minute and explained the situation, using as little detail as possible. When he found out it was medical equipment he asked if I had any good drugs I'd be willing to share.
Most of the time, people are very willing to help if you ask nicely.
