Yes Sharon, you will need an adapter but if all you plan to do with your digital camera is take pictures, all you need are some good batteries specifically made for digital camera use put in before we leave on the trip. If your really worried, take some extra as backup, but so long as your demands are simple, your one set of batteries should last.
My yearbook staff goes through four batteries a year. I only went through eight this year because one of my photographers was so in love with his skateboarding he recorded almost an hour of himself before the camera died on him. I now only allow them to use the photo feature!
If your camera dies as quickly as you say even with specialized batteries, you may want to adjust the quality of the images you are taking. But for the most part, with a 5mp camera and a 1GB memory card you can easlity take 600 to 900 pictures of good quality and size without running out of juice once. You may also want to limit the amount of time you leave the camera on either to review pictures, delete them or save them. The more time its on, the more juice you use. Also, if your camera has screen you might want to consider not using it but rather use the eye piece the old fashioned way. That will save you tons of battery life.
