After a little bit of testing, I think Attractions add quite a bit as artifacts that functions as continuous sources for die rolls.
I use the following attraction deck, split between all players.
1 Haunted House
1 Hall of Mirrors
1 Centrifuge
1 Merry-Go-Round
1 Gallery of Legends
1 Storybook Ride

1 Swinging Ship
1 Ferris Wheel
1 Balloon Stand
1 Tunnel of Love
1 Squirrel Stack
1 Pick-a-Beeble
1 Trash Bin
1 Memory Test
1 Push Your Luck
1 Concession Stand
1 Bumper Cars
1 Bounce Chamber
