Jean Scott addressed this in her latest blog:

"Having a "gambling buddy" can be an economic advantage, especially if you have a small bankroll, because two people playing the same play together don't need a bigger bankroll than the solo player."

That's true if we're considering the longterm bankroll needs of two people playing forever (and with an edge).    If two people agree to become partners for a limited time, things are different, although there is still an economic advantage to being partners.   For a trip, the partners DO need to bring a larger combined bankroll than a single player would have to have brought.

 

Consider a weekend trip in which two players each want to play 20 hours of $1 Pick'em.  For a single player, a $4000 bankroll would result in a 2% RoR.   But if both players try to play 20 hours on a $4000 bankroll, then that's the same as a single player playing 40 hours.   The Trip RoR would jump up to 14%.

 

The two partners can achieve the same 2% RoR with a combined bankroll of $6000.   So having a partner allows you to reduce your weekend bankroll from $4K to $3K while keeping the same RoR.   But it doesn't allow you to reduce it to $2K.
