We have an 18 month old and have just got back from a week all inclusive in Spain. Obviously we did just parent out daughter in a different place, but I don't see that as a bad thing and certainly not a reason to say there was no point in going. I love being a mum, I waited a long time for my daughter due to infertility and I've been dreaming of family holidays for years. Whilst I still had to do the parenting (which I enjoy doing anyway) I didn't have to cook, wash up or clean, the food was lovely and far better than we cook at home, I did no laundry for a week and instead of working all day and only getting two hours in the evening with my daughter a day I got to play in the pool/on the beach with her all day every day for a week. After she was asleep instead of watching TV and being too tired to do anything we sat on the balcony listening to the music from the bar and drank cocktails and chatted, real quality time with my husband I am usually too tired to enjoy.
On here there are many threads making out a holiday with small children is shit and not worth the effort and that hasn't been my experience at all. The journey there and back was a bit rough and exactly what I expected it to be like tbh. Other than that it's been bliss and I would 10/10 recommend people go and do it. I was kind of dreading it after reading all the threads here but I wish I hadn't worried about it so much now.
