Help! Advice on 2nd cs recovery time

ali&jonbaby

I had an emergency c-section July 10, 2011 after over 24 hours of labor and 2 hours of pushing.  This time, I will have a planned c-section to be scheduled July 5-12th 2012.  I was asked to be in a wedding for a very good friend of mine on July 20th.  Will I be able to walk down the aisle at this time?  Would be a week or two pp.  I do recall walking around the block 10 days pp last time and was okay.  Just want to know if I should pull out now or go for it.  Really want to celebrate with my friend (she was in my wedding as well).
