First, some background, Bearpath Lodging (2 private suites and a glamper) is a 220+ year old Inn/ large farm home that we have mostly restored over the last 15 years but a property that old comes with issue's, becoming an Innkeeper only adds to that list things that could possibly go wrong. The short list
-Well won't pump water, arriving early, no hot water, no heat, no Uber/ needs a ride to airport, air conditioner wont work, plugged tub drain, no power, leak in roof, arriving late, no internet, internet is slow, Guests upstairs were noisy all night and guest downstairs is angry, guest from another booking found another guest from downstairs suite in their private bathroom taking shower, guest stuck in driveway, ....
After hundreds of bookings over a few years in 3 different suites we list (and live in), Melodie and I don't get shaken up very easily by issues large and small, we have come to expect anything can and will happen any time of the day or night, our goal as always is to try to turn every imperfect situation into a 5 star stay (we almost always accomplish that). Most customers care much more about how quickly and effectively you treat their specific uncomfortable situation than they care about being in one (many of their own making). "Being right" as an innkeeper is less important than a happy customer leaving you a perfect review even after their bathroom in the Glamper was nonfunctional due to lack of water!
Last tidbit of advice, if you cannot safely and properly DIY fix your own problems at the speed of light, assemble a team of professionals that are willing to go the extra mile for you that you must do for your guests or don't even think about becoming a host.
