Simply put, you can only purchase a maximum of 24 OTUP with the BOGO offer per MMB and membership.
I will say there is still some ambiguity around what is and is not allowed to maximize MMB BOGO OTUP.
Our MMB was purchased under my husband’s name, who is listed as an owner on 2 different
DVC memberships (1 resale contract on Membership A, and 1 direct contract on Membership B that has blue card).
Call #1 - we quickly told the CM the order we’d like to do our transactions, and asked if it was possible. We wanted DH to use his MMB to purchase the discounted OTUPs on his resale BWV contract/membership, then we’d like to buy MMB for myself where I’d go ahead and use it to buy discounted OTUPs on our direct VGF contract/membership. He said no problem and it was possible. He got far enough that a phantom VGC contract showed in our BWV account… and then phone call disconnected
Call #2 - I gave the same opening but was told DH cannot use his MMB to buy BOGO on the BWV resale contract/membership.
So we just decided to get the ordeal over with and continued Call #2 and only 1 set of Bogo points with 24pts max. We really only needed 10 more so we just bought those regular price on the BWV resale. BUT, I have read many testimonies of people doing exactly what we wanted to do, and the first CM seemed to know exactly what we meant and that he’d be able to do it. Thus I’m not 100% certain if there is truly no way for DH and I to each buy a MMB on our direct contract and then each use the BOGO entitlements on different memberships

The one CM said DH
can use his for buying on the BWV resale but then that call conveniently disconnected later on lol. Which has happened to us many times before so possible coincidence?
