This depends on how much you plan on coming! We always recommend doing the 2 week trial to not only try out different instructors and times but to see how many times a week you will come based on your schedule.
If you come 1-2 times a week then a class card package will last longer. If you come 3 or more times a week then unlimited will be better financially.
Yes you can, it needs to be a minimum of 30 days and can only be on hold for up to a maximum of 4 months.
You will not be charged for your first one but if you put it on hold after that it is a $15 one time charge.
