I am taking two trips about three months apart, first a short stay and then a longer one. I'd like to try out this rental on the first one, and consider whether to rent or buy before the second. Would I have to pay the setup fee both times?
Yes, the set up fee would be charged both times. The fee covers, technician time to fully sanitize, set the device up with pressures, and test device for function prior to shipping. It will also cover some of the cost of shipping too and fourth, new accessories (filters, hose, muffler kit etc)
