Are you staying at a hotel, I would say to contact them and ask for a recommendation or even if they can organise for you. They are always so helpful. X
I would just buy a car seat travel bag and take your own !! Much easier, less stress and you know it’s never been in an accident ect -
When you go taxi stand I saw a few times some car seats on the ground I don’t know if you tell the man escorting the lines for one
A lot of car seats you hire abroad will be for much older babies and lots forward facing only. The 9kg+ will be because they forward face from 9kg which is terrifying really. I would absolutely take your own x
