My husband and I (in our sixties/active) would like to take a once in a lifetime cruise(anytime except for January this winter) of The Galapados Islands, but it's pretty confusing! I've looked at Silversea (new ship coming out in September)...various itineraries...and Avalon (two different ships...one older than the other). The Avalon ship combines land in Quito and a 4 day cruise...the Silversea one is a 7 day cruise (not from Quito). My questions are...Are there any islands that are more interesting than the others and does timing really matter? And, of course, has anyone done the Avalon trip? Any other feedback so very welcome! Thanks so much!
