Get a second dress or alter the first?

I’ll try to keep this brief…
We’re doing a surprise choreographed first dance (I’m a dancer so they’ll expect it, but we’re telling people we’re not doing anything big) and I just tried it in my dress (by myself) for the first time.
Although I never wanted a train, the dress I picked has one, and it’s grown on me. It’s not super long, but definitely long enough to be in the way while I’m dancing. I don’t like the look of a bustle and don’t think it would work with my dress regardless. So, although I’ve always said I don’t want a second dress for the reception, I also don’t necessarily want to get rid of the train. Making this all either more or less complicated than it already is, I don’t feel SUPER strongly about my dress to begin with, but I do like the little train more than I thought I would. Do I go against my instinct and get a second dress for the reception? Or maybe just for the first dance and then change back again? That feels like so much work. Or do I just get rid of the train, which was my original picture in my head anyways, even though I like it now?
