I have been looking for an activity class for DD (2y 8m), and Gymboree has recently opened here.
I phoned them last week and the Play session for DD's age group (Gym Explorers) was this morning, and we got a free session. Just got back and it was really really good. I was very impressed. Seemed more professional and organised than Tumble Tots (we did that when DD was younger). It was really well done - today was based on a Winter Wonderland theme - so we did lots of activities pretending it was winter - building a snowman, throwing snowballs, hibernating like a bear in the caves (tunnels), went inside an igloo (parachute), catching snow bubbles, jumping into puddles, riding a toboggan and read a winter story and sang songs.
DD adored it and got loads from it.
It isn't cheap though!!! Costs £89 for 12 45 minute classes. Art the moment there is a special offer - when you enrol for 12 Play sessions, you get 6 music sessions for free.
Gymboree (has a website by the way) does 3 sessions: Play, Music and Art. And there are different classes for different age groups.
I have signed DD up for Play , but on a Friday we will also do the 6 music sessions for free for now.
For your money we also get to use the free "Open Sessions" - which are on every day Mon-Sat, normally around lunch time here.
And they do birthday parties for memebers and non-mebers too which look good.
Was really impressed!
