Antarctica - a 'once in a lifetime' trip, where once is never enough!

We went to Antarctica a few years ago, fully expecting it to be a once in a lifetime thing, and we loved it. Unexpectedly, we got the chance to go again - and fell in love with it even more. I genuinely don't think it is somewhere that I would ever tire of going to, and we know we have to go again, and this time include South Georgia too.
