Hi Alessandra!
I donât know how much needing to buy 813 GuestPoints costs but yes, GuestPoints can be expensive to purchase if youâre needing a huge bulk of it. The idea of home exchanging is to also host people in your home as well which will allow you to accumulate GuestPoints which you can use to travel with.
If youâre absolutely unable to host at this point, you could also receive some GuestPoints by referring your friends and family (more information on that here).
