Long haul baby - what do need to pack?

[Mississippilessly]

We are taking our 7 month old baby away for 10 days - long haul tropical destination.

Hit me - what do I need? Taking the car seat seems ridiculous but we will have a short transfer from plane to hotel. I believe the hotel supplies strollers but not sure they would be suitable for such a young baby? He is breastfed.

Awaits the 'what were you thinking' comments because in truth I'm not sure!!!

Ok so the airline says they cant do reservations.

I'm nervous about the car seat. The transfer is s shared vehicle - it will be a coach/bus. Not sure I'm going to be able to use one on them?! We arent hiring a car.

I love our Uppababy and I have a bag for it but it is big - will phone airline again and check rules.

I'm getting stressed now which is daft because I felt OK booking it.
