hi @Carrie21
Although it sounds a good idea it would be virtually impossible to contact a meaningful number of hosts to even make a dent....
We tried inside one of our resorts, the smallest one with 120 owners, and it failed a few weeks later... in the next few months with the change of ownership and managements we couldn't keep track anymore even of the houses currently on the market...
Instead, I suggest you use any price automation tools on the market... WheelHouse, everbooked, beyondpricing and pricelabs are just a few examples... They will give you a big bump on the occupancy rate and more revenue on the high demand dates...
