We joined the Level Three Playtime class at this Gymboree for a month (you pay month to month membership and cancel when you want). It was a great way for my 14 month-old to explore while learning fun songs. The instructors are very professional and understanding even when your tot is having an off day or is not necessarily focused on the activity at hand. The activities are very safe and encourage socialization. Even though it can be pricey, there are also free playtimes as well free classes every week.
We joined this Gymboree during July (you have to join at least one month at a time). There are a variety of classes to choose from and there are many free classes and open gym times each week. My son and I signed up for the Play and Learn Level Three. The instructor, Mary Beth is very sweet and great at balancing play with songs. My tot loved playing in the safe, engaging environment.
