San Diego Zoo tours

[LacyBelle]

I know there are a few San Diego Zoo employees on the DIS and am looking for a recommendation. Hubby and I are come down to San Diego to visit the zoo at the end of April and have a decision to make....

Which would you recommend -- The Backstage Pass tour or the Inside Look tour?

We are also looking at doing the Twilight Trek that evening.

Thanks for your help!
