We had brought the Sunny Seats Photo pass on top of the show tickets and it was worth it. My 3 year old son loved getting the chance to meet, hug, kiss and take photos with both Elmo and Grover.
Reading the other reviews I thought it was exaggerating about having to spend between $50-$100 in merchandise, but it was true. A toy was $15, a t-shirt was $15, any food was $5-$10, plus the timing of bring out $10 Elmo balloons during the 15 minute intermission right in front of the stage was impeccable timing. You could almost hear all of the children saying, 'Elmo balloons!!' at the same time.
All in all, worth it seeing the great time my son had and it brought back childhood memories for my husband and I.
