jaxe,
oh, just for decor..haha.
Gymboree is like a huge play gym, but the tunnels n equipments are not permanently fixed structures. ie. they have those moveable slides, tunnels, bridges, climbing stations etc. These are used for free-play. They conduct lessons.. so when there is a lesson, they don't open for free-play. For lessons, it's the usual package type.. like 8-sessions or 12-sessions etc.. then the lessons have themes i supposed.. some got more music, some more movements etc for different age-groups.
When there is no lessons, they open the place for free-play. usually on Sundays there are no lessons it seem.. but still must call them first to enquire when are the free-play hours. For such free-play, they will then have those moveable equipments there (as mentioned above).. so u just bring your kid there to let her crawl around or "gym"..
In Singapore, i think there are 3 gymborees. One in Forum, one in Vivo and one in Parkway.. they don't have SG website.. u must go to the US site and then look up country location etc. For free-play, it's $15 per hour for non-members.. if u sign up as Gymboree member ($50 per yr) then free-play session is $8/hr.
