We booked a small local pool for DD's 5th birthday party from 10-11am.
We were at the pool as instructed at 9.50am. The guy with the key failed to turn up. In the end, I managed to find someone at another pool in the area, who knew someone with a key, to get them to find someone to come and open up the pool - which took until 10.30am.
Luckily, the pool is next to a park, so the birthday girl and her guests played there while we waited.
In the end we were in the water by 10.40am. The next booking wasn't until 11.30, so we just about got our hour but would I be unreasonable to ask for some kind of refund?
In the end things worked out ok, but it was a massive added stress.
