Should I go to the SMBE meeting?

I've been debating whether to attend the Society for Molecular Biology and Evolution meeting in June.  It's in the same place (University of Iowa) as and right after a meeting I will attend (John Logsdon's Evolution of Sex and Recombination), so practically it would be easy and I'm paying the airfare anyway.  But I'm also going to the American Society for Microbiology meeting in May (Philadelphia), and because I'm combining this with a visit to family in Florida I'll be home for only 2 days between this and the Iowa trip.  So I'll be pretty burned out from meetings and traveling by that point.

I've never been to Iowa, so few days there sounds interesting, but a week in a small college town surrounded by cornfields?  I suppose I could get a lot of work done.  Dates:  Fly in May 31, Sex meeting May 31-June 3, SMBE June 3-June 7, fly home Sunday June 7.

Also, registration for the SMBE meeting is $450.  But accommodations are cheap, especially if I stay at the Motel 6 ($36/night).  But staying there would require renting a car, which would be fine if I wanted to do a lot of sightseeing, but I don't think there are many sights to see (though I'd like to drive over and look at the Mississippi).  I could stay on campus for about $75/night, which is still far cheaper than what I'm paying for my ASM accommodation.

On the other hand, I just got an email announcement that the SMBE meeting will include a symposium on the impact of next-generation sequencing methods for evolution.  As the CIHR and NIH proposals I'm planning will include massive sequencing, this sounds like something I should attend.  And other symposia look excellent too.

I need to decide by April 5 to get the early registration discounted fee - otherwise I'd pay $50 more.
