I would not worry too much. If your courgettes plants are healthy and you are away for a week and a half you will likely have half a dozen of similar size waiting to be harvested on your return. So if the worst happens and this one doesn't keep you are unlikely to miss out.They really are amazingly productive and grow rapidly at this time of year. In the past few weeks almost every plot holder including myself starts conversation by issuing a cheery "good day" followed by "would you like some courgettes?"
Take it with you? Any attempts I've made at pickling or freezing courgettes haven't been very satisfactory ... but freezing is definitely better!
