The road was jampacked, there were people camping out in the grass and stuff. During the dance many groups broke off from the chain and started their own little dances in the middle of the road inviting others to join. It was fun but the whole thing only lasted for about 5 minutes.
I stayed at the Marriott Hotel Armenia and thought it was very good. Is that ranked as the best currently? I saw a few others, Congress, Golden Tulip Hotel Yerevan, Ani Plaza, and more... I don't know if those are any competition.
