I agree with the others, if you've walked on one, walking on another is the same thing. The only difference is the scenery.
But I would skip the brewery/tram/walking tour. Do it yourself. The Mt. Roberts tram, in my opinion, is definitely not worth the time or money. If you want to ride up and hike down, that's one thing, but overall it's just not worth the price. And you can do the brewery & walking tour on your own - just get a good guide book with a map and you're good to go. Juneau is not that big.
