I am in the same class at Frontier as the earlier poster, klone. I applied in Feb 2010 for the August 2010 Frontier Bound. Although you are finding out your acceptance 6-8 weeks before Frontier Bound (required on campus orientation), the classes don't actually start right after orientation. My orientation was August 23-26, but classes didn't start until September 27th.
As far as planning goes, as soon as you send in your application, ask for those days off work. Worst that happens is you don't get in, and you can cancel those vacation days. Better than not doing it, and then when you get accepted, its too late to request off.
As far as the wait list goes, I will tell you my wait list story. I applied to class 80, but there was an overflow of accepted students to class 80, so they admitted me to class 83 instead. (along with several others, and they ended up closing class 83 admissions early b/c of this---so apply early). I was on the waitlist for class 80, while definitely being admitted to 83. I found out because the day after everyone was posting on facebook that they got their acceptance emails (and I hadn't gotten one), I called the school and they told me the wait list info/admitted to the next class. This was late June. I called a few times to check on my wait list status, and was told that no one had dropped so i was still wait listed.
I still had that week requested off, just in case i got off the wait list. One week before Frontier Bound, I emailed one more time to check on wait list status, reminding them I had time off, and travel was not an issue (6 hour drive, so no flights to book or anything). I got an email back saying someone had just dropped that day, so I was in! So exciting
I am so glad I did, too, b/c I am with a great group of women.
MOre advice-get on Frontier's Facebook page. They often post updates on when they are sending out the acceptance emails. For example, today they announced that Class 90 CNM acceptance emails would be going out today, while FNP would be going out later this week. Get on their discussion boards on FB, too--meet other potential classmates
and yes, skype and facebook are invaluable for getting through this program
