Sunrise Safari vs. GG Celebration Safari

[IMGONNABE40!]

We will be a grand gathering staying at AKL--don't intend to stay concierge. The only reason I would consider concierge is to do the Sunrise Safari. However, since we are GG, we can do the Celebration Safari as a group. From what I read, they seem very similar, except one is for breakfast before park opening, and one is for dinner after the park closes.

Has any one done one or both of these and can offer feedback? For those who have done both, which would you do again and why?

Thanks.
