I took a look at the new version at the bookstore. (No point in buying it since we're leaving in 1 week and won't be going back again for a long time!) Keep in mind I didn't read the whole thing cover to cover, but for those of you wondering how much info is new, I can tell you there does seem to be a decent amount of new info. There's more details about rating of resorts; they now talk about issues like beds, pillows, noise level, etc. There was some new details about dining and attractions, but these were generally just updates of previous info. If I was planning a trip months in advance or making multiple trips in the next year, I'd probably buy the new guide. If not, I'd stick with the old one and update myself online!
And sorry, I didn't even look at the Universal Studios section since we're not going there on our own trip, sorry!
