Hi,
We are going on our first ever cruise on Odyssey of the seas in August round the Greek Isles.
I've been recommended to go on an excursion in Santorini that takes you for a walk round a part of the volcano with active craters - steam and the such. Then for a swim through some warm springs in the sea.
I can't see this anywhere on the list of excursions offered by RCI, am I looking too early? Do they add further excursions as the year goes on? Or is this no longer a thing?
Thanks
