I usually print mine in 12 x 12 matte finish from a place online called Scrapbook Pictures. They are $3.49 each and frequently go on sale for $2.49 each, and they charge a $2 flat rate shipping charge regardless of how many you order. I've printed from Creative Memories also to compare the quality, and I feel it is comparable. I have been very happy with them. The website is here:

DCL cruise this time, though, I think I am going to print a bound StoryBook from Creative Memories or Shutterfly because I think I am going to have a ton of pages.
As far as cost, I do think digital is less expensive. I went a little crazy before our cruise and DL trip and bought a bunch of digital kits that I knew would be perfect for the diffierent things we were doing... So I did spend some $$. But the big digital kits that are jam packed run around $5 each, so they are affordable. I could walk into a scrapbooking store and easily spend $50 on a little handful of papers and stickers. The beauty of digital is that once you buy it you can reuse it over and over again... recolor it, resize it, etc. etc. I love that. And I LOVE that I don't have a mess to drag out. I still use my traditional supplies for making little quick gift albums, cards, etc. There's some good info. on the DIS Scrapbooking Thread if you'd like to look around....
