Recognizing the vital impact that play has on the healthy development of a child, on Saturday, June 25, all Gymboree Play & Music locations will celebrate the National Day of Play. While Gymboree typically charges about $80 per month per class series (plus there is an initiation fee), you can check out any location between 9 a.m. and 4 p.m. for FREE. Children can enjoy play, art, music, refreshments and more. We heard about this promotion from Salima at the Gymboree at 5046 E. Hampden, Denver. But you can find the nearest Gymboree location here.
