We, too, will have one day in Manta from a cruise ship, in March, and I have read the old posts suggesting going to Montecristi. The ship's tours seem to be very expensive, expecially since they are only offering transportation by Chivas (?) for $149 a person, and the rest of the time you are on your own. Would it be easy for us to find transportation to Montecristi on our own, either by bus or taxi, and what should we expect to pay? Can you still use US dollars, or do we need local currency? Also, is it safe to walk around Manta on our own during the day? I should point out that we do not speak Spanish, and are seniors.
