If you do the aerobatics course then you will undoubtdly be tought by one of the senior instructors (most likely either the CFI of H of T). These guys don't genrally teach the normal flow of students on PPL's, CPL's etc so you shouldn't have any problem with 'fitting into the schedule'.
The aerobat is generally only used for such courses and for the odd student that requests it for hour building, so aircraft availabilty should not be a problem. One question to ask would be how many hour builders they have using the 152 as this is the only thing I can see affecting your schedule.
It is a lot of fun so enjoy!
