DD was absolutely not hotel-suitable until she was nearly 8.years.
As a baby, she woke up at ungodly o'clock and demanded food. I didn't fancy doing bottles at 6am in a hotel room. Later she still was up at 6am, preferred a normal bedtime or it was 6am the next day and utterly overtired. Sleeping in the pram was a no-go for evenings.
We had great holidays with self-catering, Devon, Majorca, Isle of Wight, Germany. A nice flat/cottage/villa with a washing machine, high chair, cot.
We did hikes with her in a back carrier, played at the beach, went to the zoo, park, pool, museum, castles, stately homes. But we did all these things at home so it was just a different location. We live in London and she had her first museum visit at 8 weeks.
Any holiday won't be what you did before. Even with taking turns, it won't be the sipping drinks at the pool, it will be platying with her in the splash area.
