You do not need to have the photos developed at all. Get an extra memory card. I'd suggest at least 64meg (about 200 "photos" at mid range resolution).
You can view your photos directly from the camera, or better yet plug the camera into the cabin TV (all cameras come with the connector...it's easy) and view that way. You can also delete the duds this way and have more room on the card. Most cameras have slide show programs built in as well I think.
When you get home you can download to a computer for viewing. The camera will come with a photo viewer program to set up slide shows, etc.
If you want hard copy prints of your favorites (why bother printing so-so shots right?) you can print on your home printer with photo paper. If you don't have a printer than Target stores or any photo dept. will have a setup to print from the memory card.
And you can put them on a cd as well if you have a cd burner and most computers have that if it's newer than about 5 years.
My guess is also that if the ships can develope from the memory cards they'll overcharge you.
And a digital camera hint. Get extra, spare rechargable batteries. You'll regret it if you don't.
Digital is certainly the best way to go this day and age....good luck.
Also another tip....get at least 2.1 megapixels. This size can be printed very sharply up to 8 x 10 size without quality reduction.
