We purchased it perhaps 3 months ago in prep for a trip later this year, and we found it very helpful. We have also found, over the past few months, the changes going on at TDR (Fantasy Springs opening, new package options, etc) have made our version of the Guidebook no longer accurate on everything - but I can't blame the author for that. It's like getting a guidebook for WDW 3 months ago to learn about
Genie+ and have the whole system change later this month! Our TDR guide has a published date of Feb, 2024, and is listed as the 2024 Guide. Looking at it now, it's still 85% accurate and helpful information. Fantasy Springs info is old. It might be a good place to start, and then purchase again next year for the updates (unless they decide to put out an updated one this year with all the changes). Bottom line - good information, not a major investment - it was very helpful.
