ABSN Program Advice/Thoughts

I am in software sales right now, leaving to go through an accelerated nursing program. Previously worked in medical field and know what to expect from the nursing job itself. But what about the accelerated program? Is it like normal college but more classes per semester? Do we still get a holiday break for a week between semesters in winter? My program is 14-16 months. I know I'll need to be organized, mentally prepared for school over social life etc. But I'm not fully sure what to expect from the program throughout. I know every program varies slightly but can you give me all of your personal experience, current or past? I know it will be worth it.
