Any suggestions for fun places to bring a 21 month old in downtown Bangkok? The Siam Paragon aquarium is on the list, but apart from that am not familiar with kids' activity areas. Preferably places along the Skytrain, whether indoors or outdoors. I have a few errands to run (medical checks etc) so some downtown places where she can be kept occupied for a few hours will be handy. Not looking for town outskirts destinations, as we have a separate beach trip planned.
