Have done most holidays alone i think as it cuts down on faff enormously- no need to make compromises or show up earlier to places than I like to, no one to reassure about logistics etc.
But with Jnr, well the faff is higher and the enjoyment level is reduced by having no time away from her at all and adapting things to her routines and tantrums. So not really into holidays much right now, but when she’s a bit older and I wont live in fear of her running into a road or not being able to swim then I’m hoping for higher enjoyment levels to return.
