What happens to bookings if membership not renewed (closed)

We have a few bookings at Rowntree after our current membership runs out. As this site is also available to non members will our bookings remain if we don't renew our membership and become non member bookings and rate? I don't intended renewing our membership when it runs out in May as we will be out of country until July and first booking isn't until Aug, it makes more sense to rejoin for Aug for a year as by Aug 2016 hope to have moved overseas so wouldn't then use CC.
