memberships

I'm planning a bit of travelling and will not be able to access a computer for at least 8 weeks. I was wondering if it would be easier to terminate my membership and sign up again at a later date when i return from my travels or if there is an option where you can 'put your membership on hold'. By this I mean can you just pause your membership where you are not able to access classes and things but are able to re-activate your membership and resume payment at the click of a button. Also, I want to make sure that it is possible to re-enroll if terminating and signing up again is my only option.
thanks so much
