I go on them all the time with my girlfriend, especially on hot days, nice and shady in Bugs Land. When I'm in Disneyland/DCA I'll go on any ride/watch any show no worries!
I'm sorry but Heimlichs is the worst! I can't stand that ride! The lady bug boogie is fun and Fliks is fun but all three ar eboth so short. If I waited more than 5 minutes for any of those rides I would feel very disgruntled.
