I reserved a place at a nursery (and paid a hefty deposit to do so!) but we've found another nursery that we like better and is much much cheaper (enough to offset the lost deposit within a month).
I feel bad about pulling out of the other place, although it's still several months away from when we were due to start. Their cancellation policy for children once they've started nursery is 4 weeks notice, so we'd be well within that. Is it a bad thing to do for the nursery, or will it be ok with enough notice.
