So, this place was constructed around 1977 or so, and doesn't really seem to have gotten an update since then. That's generally OK for the main house: nice colonial architecture in the main hotel, however the whole thing needs a massive upgrades. Pretty grounds which are filled with swampy, mosquito-ridden pools. Decent restaurant, esp if you stick with the Indian food. If you are going to insist on chicken nuggets or a caesar salad, then you are on your own.
If you come here, you must do a boat tour. It makes a perfectly fine base for exploring the backwaters, but is honestly not a place I'd want to stay more than a night or so.
Plenty of animals (rabbits, flying foxes, geese, birds) to distract the children, if that's your thing.
