Activity recommendation engine

My client and I have been working to create a way for people to easily find recommendations for things to do with other things. Like, "Go to THIS bar and then THAT concert" or "Camp at THIS campground and then go for a hike on THAT trail."

There are a few things I needed to solve:

1) Choose an initial activity to see options for other activities that go with it.

2) In an activity, see the specific places, shows, movies, etc you can do.

3) Integrate seamlessly with the main app experience.

Here is the result. Once you find a combo you like, you can immediately create an invite and start collaborating on it with other people
