I have 2 kids myself, grown up, so I have been a parent on holiday too.. 8 pools in the hotel, including special kids pools.. Children welcome and catered for at 7 of those... But people insist on using (with kids) the one pool officially designated for adults and designed to be quiet... The "relax pool". Not relaxing with children screaming and splashing.
AIBU to think it's slightly selfish behaviour on their part?
