I’d be asking for a full refund.l if you don’t think rescheduling will suit you

I am a photographer and although I’ve never had to cancel a job for anyone yet if I were in that position I’d offer to reschedule (and if its short notice I’d make sure you got something extra in the package free), or if that wasn’t possible I’d refund in full. For me it would be as much as my reputation as anything else.
