Ahwatukee, It looks as if you are trolling numerous sites and asking this question which is a good thing to do. But if I may suggest.
- Nobody has higher exposure (SEO) than VRBO.
- VRBO has a wonderful system called 'Reservation Manager' and pretty much does everything one would want in responding to inquiries, booking, billing and receivables.
- While VRBO is expensive I look at it as a cost of doing business and only one weeks rental. I am always 80% booked so I am quite happy.
I would suggest if you are not already a user of VRBO to go ahead and join up and get heavily involved with Reservation Manager.
