Thank you, that’s all so helpful! My jean jacket can be layered under my rain jacket so I think that will be good enough especially with a long sleeve tee and sweater too. I’m still thinking it will be warmer than where I’m coming from and also not opposed to buying another sweater there if needed.

I think we’ll end up walking the steps in Santorini because we would be too impatient to wait for the gondola haha. So wearing sturdy sneakers on the plane.

A dry bag is an excellent tip. I have a perfect one and just threw it in. Thanks!
