vacation in middle of mcat studying

Hi all,

Does anyone have experience with having to take a trip in the middle of studying for the MCAT? I am scheduled to take the MCAT May 13 but I do not feel ready so I am looking to reschedule sometime in June. I have a one week trip I need to go to from June 1-8. Would it be a bad idea to take the MCAT June 17? Should I push my MCAT to June 30th?

Any input would be great!
