I escorted my grandma, who was 78 at the time, with a group of Catholic elder ladies and an Italian priest on an excursion to Fátima. It was quite odd, I only recommend it for the really devoted ones. But it was fine, for after 5 days the group came back to Brazil, we paid a fine and spent a couple more days traveling around other cities. Eventually, grandma confessed she had her dream come true, but that the following days had been the most fun.
