Unfortunately, Princess is not currently (as far as I know) posting prices of cruises, other than under their "specials" heading. They are quite committed to TAs in this regard. I also sail HAL and Celebrity and they do post prices, should you want an idea of comparison. Just call your TA for any Princess offering you think you might like; I'm also in favor of TAs even though I do check the websites for an idea of prices. I think TAs are valuable for a lot of other details and because they do hear of deals or good prices in general, and believe some of the great upgrades I've gotten are at least in part due to using a cruise only agency. Good luck!
Hi, first timer too! I found a pretty helpful site for checking cruise prices to be www.cruiserewards.com. I was able to compare several cruises there. Now don't know how accurate these prices are but at least they gave me an idea.
I would check travelocity, because that way you can compare easily. The only problem is that the cabin selection is limited. Also, if you go to the site one day, but then decide to buy several days later you aren't likely to have the same choice in cabins. They seem to change frequently. Unfortunately, I found that cruising isn't quite up to speed with the internet, it seems much easier to use a travel agent. I ended up using one, and got a much better cabin for a much better price than I was able to find on the internet when all was said and done.
