Print up as many bingo cards (like the one you see here) as needed. Everyone playing looks for the items on the card as they travel, and check them off as they find them. If you want to use "five-in-a-row" then be sure to print out different arrangements. This particular card (and others like it) can be found on www.alltravelingkidsfamilyvacations.com, but there are plenty more all over the internet.
