Excellent job - you'll need very little to supplement this,
This review is from: Eyewitness Travel Guides Venice And The Veneto (Paperback)Eyewitness did its usual brilliant job with Venice & Veneto. I bought many guides available to this city but took only two with me: DK Eyewitness and City Secrets (the latter one is an excellent assortment of subjective specialist views, get it if you take your trip seriously).
Descriptions of usual high-profile highlights and lesser-known places are clear and accurate, as usual, pictorial plans of churches and streets are very helpful.
Accommodation and dining sections are quite superficial, I increasingly find these parts not the strongest bit of Eyewitness guides: they tend to focus on most famous places which rarely represent the best value for money and often are shameless tourist traps. In fact, there is no need to list specific places - what the guide could do is present general guidelines on what to avoid (such as places with menus in five languages) and what to look for (places that don't take credit cards, for example).
I found the map of Venice at the end of the book completely sufficient and as easy to use as could be possible in the Venetian maze of streets of multiple names and multiple spellings.
Veneto part is not really the best bit of the book - Verona is covered only adequately and Padova receives simple an inadequate treatment. The authors probably had to find a balance between thickness of the book and depth of coverage.
I was pleased with coverage of less obvious areas such as Dorsoduro and Canareggio, which are still inexplicably ignored by 90% of visitors (well, maybe they don't have time).
All the criticisms above are observations of only minor glitches of what is a very, very strong guide and what probably should be your first choice for a trip to Venice.
