NBR: BFF's shower and moving on the same day

I'm hoping you ladies will have some suggestions for me!

In the last 2 weeks my BFF decided to move her wedding up from Nov 2012 to April 2013.  This means her bridal shower has been moved up too of course.  I was orignally supposed to be in her wedding but now they aren't having a wedding party anymore so I don't have to go to the shower but I really want to.  The issue....we have to move the same date!  She has known for 5 weeks we were moving that day and was supposed to watch DD for us. I don't feel like she should have planned it around me but I think she will be upset if I don't make it. 

I can't decide if I should go or not.  The shower is 2 hours away. I would have to get ready amoung all the boxes, pack up DD, drive 2 hours, stay at the shower for 2-3 hours then drive 2 hours home.  This would leave DH to move everything mostly by himself (her fiance offered to help in the morning only).  When I got back I would have to come deep clean our entire apartment (and I'm assuming I would have to be done by 5pm when the apartment office closes).  Does anyone see how this could work? Would it be horrible of me to not go?  Should I try to stay in our place one more day so I can go?
