We are planning on doing a 4 night Australis cruise this fall and I'm trying to decide between the October 29 low-season cruise on Stella Australis vs. high-season Via Australis cruise on Nov. 8. We could also do high-season Stella Australis cruise on Nov. 5. The cabin size seems better on Stella Australis and bigger windows in cabins and deck spaces but there are more people; the Via Australis 11/8 has smaller cabins but fewer people. Any preferences? Any suggestions re late October weather vs. early-mid Nov. would be most appreciated. We'll be going to Explora Patagonia just before the Australis cruise so the weather (Oct vs. Nov.) matters for that too. Thanks.
