Using Ashley's brilliant idea,
How about,
1. The park is a single path from the entrance down the middle of the park that splits into Bo's and Ed's zones.
2. Before the livestream each can place 1 ride and 1 shop so there is something to start with.
3. Each take it in turns of say 2 minutes to choose a blueprint and place it in their half.
4. This carries on till they run out of time.
If this can't work to find which half has made the most money or the highest rating, how about all the viewers vote on who's half is the best and one of the viewers who voted for the winner wins a prize?
