I am in the preliminary stage of planning a Ecuador trip. At first I was centered on the Galapagos only. However, since there is so much more to Ecuador that we would like to experience, we are looking into extending our trip to other parts of the country. In order to financially do that, we are considering a 5 day 4 night Galapagos cruise instead of a 7 night cruise while understanding that the first and last days are really just fractions of days. I'd like to hear from those who have done 4 night cruises. What ship? What time of year? Thanks for any information.
