The best Camp Snoopy, by far, is the original at Knotts Berry Farm. What makes the version at Knotts so great is that it is heavily saturated with big full trees, and the overall theme is woodsy (camp) and rustic. Its been overhauled a number of times - but the current version is superb.
If KI must stick with the Snoopy theme, I too would love it if KI took the time to do a similar overhaul to their current kids area. It would require KI to completely gut the entire area, but if they did... it would be spectacular. Also, replicating the theme at Knotts would definitely compliment the now waning Rivertown theme... and could easily be blended to make the two areas cohesive and complimentary. Finally, Boo Blasters is crying out... no, SCREAMING... for a Snoopy themed dark ride.
