Auggie, I will spoil the twist below, but if anyone is planning on seeing the show I would suggest not reading it...
SPOILERS ON THE TWIST********************************************
At the midway point of the show Boggess and Burtka actually do get married, despite Josh Grisetti (Boggess' ex) showing up in an attempt to stop the wedding.
Boggess and Burtka slip away to a private room with Glover and Splanger (the co-maid of honor and best man) and proceed to start kissing their gay pairing. Yes, they both are gay and in 2015 decided to have a huge sham wedding so Burtka could obtain access to his trust fund, which his bigoted grandfather only would allow to happen after he married a woman.
The plot point is so ludicrous and far-fetched, and of course negates most of what we just saw in the proceeding first half. As much as Boggess tries to explain her actions it's just too much to believe. The show turns from campiness to Boggess singing a coming out ballad. It's just all over the place, throwing spaghetti against the wall to see what sticks and all that's left at the end of the night is a messy wall and a pile of spaghetti on the floor.

Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
