Because the rental companies, if they actually are owners of points, and not the rentals by owners, are limited to how many memberships they can have and points owned. They also give renters access to the accounts. They, the owners, do all the booking.
They are also limited by the number of accounts that can be set up to access that one set of points at a time.
With a trust, unlimited number of accounts can be set up to access the same set of points at the same time.
Instead of you and I who are capped at 4 associates…which is probably how it works for the rental company accounts…this would not.
And that means different rules. Think of it this way, I have VGF and RIV points in my Dec UY…no matter what, I can only book one room at a time…until my points are gone. But, what I can’t do is book multiple rooms for the same date at once.
A trust is different and allows multiple people to book the same day with one set of points. So, that is a conflict for me.
ETA. I even tried to have my DD and I try to book the same dates with our individual accounts…same membership and one of us always got the dwarfs.
