Hey,
I think it still feels like a holiday, especially as you have your partner around all the time so you can share parenting duties more. The tips for enjoyiing area really just to be flexible. Not too many "must be here by this time" so ****tails by the pool sounds awesome.
If you manage to relax your DD will hopefully pick up on it and relax too. Sleep might be weird so just ride the wave.
At 13 months you're still your bubs favourite toy. Books are always good.
I look forward to hearing how wonderufl your trip was!
