Just read Gold #30 in full. I was expecting it to be a poorly written issue...it actually was quite good, and it had a nice flow to it. Artwork was amazing, the moonlight scenes with Kitty/Colossus and with Magik on the rooftop was beautifully lit. Guggenheim somehow wrote everyone in-character. No "boyos" from Gambit and held back on the "sugahs" for Rogue (she only said it once). In fact Rogue and Remy's interactions were in a similar tone to Kelly Thompson's writing, I heard that she tweaked a few things and had some slight involvement in the script.
Initially I thought it'd be like Chuck Austen's disastrous Alex/Lorna wedding which was one of the worst things I've ever read in an X-Men book. Although Kitty comes off flaky...I actually thought Colossus handled everything quite well...I genuinely felt for him, and came off rather okay in a terrible situation...Kitty probably not so much, but we'll see in #31. Perhaps Magik was a little out-of-character herself.
Overall, the interactions between characters were mostly enjoyable. For the finale, well Rogue and Gambit's sudden marriage after reading this felt natural to me, they are spontaneous characters, it's something that they would do...and we'll see some more insight in MrMrsX #1.
