AIBU to go on holiday without toddler

[10thlittlemonkey]

I was thinking of booking a short all inclusive break (3-4 days) with my partner and leave my 2.5year old with my parents. She has had a few sleepovers with my parents and has recently had a 2night sleepover which was uneventful, but she was quite unsettled with her behaviour when she came home- thinking maybe a bit of built up emotion but could also have been just normal unpredictable toddler stuff!
I was talking about this with a colleague and they suggested that they would NEVER have their child miss out on the experience of a holiday and as a working parent, it is most important to prioritise time together as a family. Whilst I agree with this sentiment and do love our time together as a family- I am just really craving some relaxing pool days and being able to have an few days of uninterrupted food and rest.
AIBU for considering this?

100% do it OP. We first left ours for a 5 day holiday at 9 months.

DH and I went away for 12 days when my kids were 2.5 and 4 years old. Best thing ever. We did sometimes miss them and think how great it would be with the kids there, but honestly all it took to change that was a stroll by the family pool: crying and miss behaving kids, parents scolding them, parents arguing with each other.. 😄 No thanks!

It was a really nice holiday just the two of us. And it really brought us closer again.
The kids both loved staying with my parents. They got to face time us when they wanted and although they did sometimes ask about us, they didnt really mind that we were gone. They have a great relationship with my parents though and are comfortable staying there.

My kids are 9 and 11 now and they have overnights with grandparents or my siblings quite often. We never went away without them for that long again, but we had a 4 day trip once after for our anniversary.
