Here is the first phone call of my day.
Caller - "My grandparents own timeshare at your place.  We were wondering if we can exchange their week for a week in May?
Me: "Let me check the availability.  What week in May do  you want?"
Caller - "May 3rd"
Me - quickly without even having to look said "I'm sorry we are completely committed that week.It's the 2nd week of Jazz Fest."
Caller - "are you sure?"
Me - "yes, it's been booked for a while now."
Caller - "There is there anything you can do?"
Rolls my eyes and thinks to myself: "Sure, let me just kick out the owners who paid premium prices to own that week and have been coming for 20+ years?  Or let me kick out the others who made reservations 6+ months ago.  Better yet, why don't I just build more rooms in next 3 weeks?"
                
What differentiates an average host and a great host is anticipating unexpressed needs and wants of their guests.  Just because the want/need is not expressed, doesn't mean it wouldn't be appreciated.
