I am sort of loathe to use X fares. But my family of 4 is making a run to LA and the savings is 25% off and there are open seats available so I know we can sit with the kids. I am MVPG and spouse is MVP. But we are not really interested in upgrades away from kids. Is there really any benefit to Main aside from back of the bus? (Its a little over 2 hours so no big deal.) I will just check bags and board with MVPG and call it good I assume.
