Antarctica Cruises

I'm looking for some info about ships to Antarctica this coming January. Does anyone know about smaller cruisers, costs and availability? I understand making reservations can be a good idea, however, smaller ships are available at the last minute.Am I correct? Any info from travellers or expats would be greatly appreciated.
Hi Steve,I'm just starting to research trips to Antarctica myself and maybe we can pool our resources together and help eachother out. So far, I've found a lot of info online but I haven't been able to talk to anyone who's made the trip. You can email me here: Michelle
