The post reads "Guests who book shorter stays tend to cancel less." I disagree, people that book for longer stays have more invested, those for shorter stays will cancel if the weather is not good,.
From my perspective since 2000, my experience is totally the opposite! I would challenge this statement and suggest this is written by someone without much experience,
Additionally, "opening your calendar to same day reservations"
for those who call either first thing in the morning or during breakfast tend to be people that have chosen a place that does not meet their expectations, for instance a noisy Air bnb, or one infested with BedBugs, this happens,
Therefore be aware of last minute requests, my advice, have Hotels handle this, they are better equipped with Extermination Procedures which for a small BnB can create turmoil and alot of hassle; just for a day or two rental,
