Top Hosts near MT, United States
Michael provided my husband and me with “Rosie” after he had to cancel our original reservation for “Judy” two days before we were scheduled to begin our trip to Moab, Utah. After some panic, we arrived in Las Vegas and picked up the van and began our drive to Moab to meet up with our son and daughter-in- law for a week of camping and hiking. Despite some pretty annoying electrical problems with the van throughout the week, we did have a wonderful time. This was, in part, due to my husband’s and son’s abilities to figure out some ways around the issues, but also because of Michael’s prompt response to our texts and phone calls and his thorough knowledge of the van. We couldn’t have asked for a more responsive and concerned host- thank you for that. And thank you for scrambling to get us into a van that provided us with such a great week as a family.
