That has not been our experience at all to be honest.
We've been lucky enough to travel extensively with dc from when they were less than 12 months (Australia).
We loved experiencing life in other places though the eyes of being a family as opposed to what our pre-kids travelling was like.
We still managed to do a lot of eating out, even enjoying regular glasses of wine at sitting out in the evening warmth etc
We always tried for a balance between something we wanted to do - museum / gallery / walking tour and things dc like - playground / parks / beach/ swimming. That way everyone was happy.
Lots of breaks for icecreams and we stopped at every park / playground / green space we came across so dc could have a run around and we'd have a take out coffee / cake
When dc were very young we always stayed in apartments unless it was only an overnight. That gave us great freedom to have breakfast at home, have a separate room for them to sleep. A small kitchen to whip up pasta / toast if they got peckish. A fridge to stock up with wine / milk / snacks
Dh and I relished these trips and always had time alone in the evenings. Some of my happiest memories are of us all heading off somewhere new and getting the dc excited about all the things we'd see / do. We've only ever done 1 dedicated beach type holiday in all the years which was to Majorca and even then we incorporated 3 days in Palma city centre before heading to the seaside village.
We've had wonderful family adventures with the dc in many places including Berlin, Prague, Venice, Paris, Budapest, Lake Garda, Canada, Australia, Thailand etc
