Once you get out of the United States, however, you can live majestically on an average of $1,000 a month, provided you stay away from shore and out of the marinas. When you're out on the hook, fishing for your dinner, eating from your stores, and keeping your wallets in a drawer and not your pocket, you'll have what we call "Zero-Dollar Days." This was especially easy to do in Cuba and Belize. However, whenever we've wanted to go ashore, or explore inhabited islands for a few days, the wallets come out of the drawer, go into our pockets, and money seems to gush out at an alarming rate, as some strange compulsion to buy previously uncoveted things seems to take over temporarily. Plus, we rented a car while we were in Mexico and went inland to explore, and to see the Mayan ruins of Chichen Itza—an expensive proposition, as we left the boat in Puerto Aventuras Marina and stayed in hotels for a couple of days. Still, it was an experience we wouldn't want to have missed. However, Guatemala is downright cheap; while traveling about, we rarely spent as much as $30 a day, and that includes the $3.65 a day to keep Ithaka at Tortugal Marina.
