Hi Karen. Val & I aren't on this Adventure, but I wanted to suggest you pick Farmers Market. We've done all three of these and the bus tour was our least favorite. You'll see enough of the Hollywood area on the actual ABD. If you try one of those tours that promise to show you where the stars live all you will actually see are big fences and solid gates behind which star X sometimes lives...or used to live. If you're lucky they will pass around google earth pictures of the estate.
In & Out Burger has a huge following but we just don't see the attraction. Its simply a fast food burger joint and is not up to the Five Guys standard that we measure these establishments against. I know that comment will get a lot of push back by the I&O fans. But consider this - a 15 minute experience there isn't a huge time occupier. Even with the uber ride to/from the location.
The Farmers Market won't cost you much more for the uber ride but the number of choices to eat at runs into the 10-20 range. Some really good choices there. Plus some very interesting shops. We enjoy Monsieur Marcel for gourmet foods. On the other end of the spectrum, but equally good, is Bob's Donuts. Right next to the Farmers Market is The Grove where you'll find several mall type stores to browse in.
