My mother was a health visitor and one of the mums she visited told her about this great place they loved to go to for holidays. We took her advice and ended up in the Solway Lido. It was horrible the bedclothes were blankets and they stank by morning the rooms were terrible . We stuck it out almost to the end but DS was sick in the bed ( he had mumps ) so we gave up and went home .
Anther holiday on a farm in yorshire the cottage was OK but hasd a load of small faults and old uncomfortable furniture. The kids from the farm got friendly with our and one day the daughter went to our toilet and complained about it not working properly . When we hot home I listed the faults and told the agency we booked with . They took the place off thier books and gave us a cut price Autumn wee which turned out to be one of our best family holidays.
These day I check trip advisor and would make a real fuss if things were bad.
Things you find stressful that other people don't notice.
