We were 10 plus when mum and dad started going away for 2 - 3 night trips. My grandparents were elderly and it was a rarity we were both left with them for multiple nights. If they went on holiday it was usually a qualified child minder.
Truly, I do think it's odd to have children OF THEIR AGE and be going on a week long trip anywhere, let alone the children's playground of WDW. Then on top of that, add into that the uncertainty of Travel due to Covid.
It would be risky with a childless couple who need to come home and get back to work etc let alone these two fools.
I've unfollowed as I truly think Sian and her "money saving yet so perfect" lifestyle really grates and is toxic, but I did see her story reel about friends. Just oh my god, what a pat.
