BabyBelle is right, you can make improvements on your personal statement (I don't know why anyone would keep the same one anyway) to show your growth since your last application. You will have to pay PharmCAS again not to mention all the supplemental fees as well...
I went through that same scenario last year. During my senior year I was only able to apply to a very limited number of schools due to pre-reqs. Being from California, I didn't take the PCAT and basically limited myself to California schools. I got accepted to a couple schools, but they weren't truly the schools I wanted to attend and I couldn't get excited about them. So, by default, I took a year off. I had a tech license before, but never really had the chance to put it to use, so that's what I did (and still do). I took more classes to fulfill pre-reqs such as physiology lab and microeconomics and picked up another job to kill time. I also took the PCAT this past October. The decision I made turned out to be great because not only was I able to bolster my resume and write better personal statements, but I was able apply to more schools (and thus enhance my odds of being accepted).
Coincidentally, my stats are really similar to yours. I graduated with a 3.6 and had a composite of 91. I applied to 9 schools and got interviews to 8. I interviewed at 6 of those 8 schools and so far have been accepted to 4 of them and waiting to hear back from the final 2. So, even if things don't go as planned this year, don't despair, because I'm sure you will make the necessary adjustments to make yourself an even better candidate that you are this year. Your GPA and PCAT scores are competitive enough for every school in the country, so if you have to take a year off, persevere, work hard and show the interviewers how you've matured and grown the past year.
