My FMIL wants to use the same theme as my wedding (travel/maps) for the shower. I'm not wild about this idea. Am I wrong? Should I just let her do it? The hosts of my other two showers (yes, I have three in three cities) just want to use the colors, which I thought was more traditional. The biggest thing that bugs me about this is that I've put so much work into coming up with this theme, making it unique, etc. and she's like spilling the beans before the wedding even happens.
