Upon further investigation of the giant tents, it was Cirque Du Soleil... "Luzia!" Watching people exit, we finally approached a group and asked for their thoughts of the show. Hearing things like "I've seen them all (Cirque Du Soleil shows) and this is THE BEST EVER", we decided it was a done deal...time for a major distraction, of circus tent proportion.
Success! Can't say it was a officially a 'fun' trip, but one with welcome and magnificent distractions : - )
