Tour company questions

[Funbobbi]

I am planning a day trip to Sea World from Anaheim. I am not renting a car so I was planning on booking a bus tour. Has anyone used Grayline tours before?? What other respectable companies would you recommend? Thank you.

I've only used them for their Disneyland Express service, and if I were in your shoes I would use them for SeaWorld. Grayline is a known company.
