Advice needed on visit to Ambanad Estate / Ambanad Hills (Kollam, Kerala)? Worth it for a family holiday?

I’m trying to find real information about Ambanad Hills in Kollam district, but surprisingly there’s very little online.

I heard it’s possibly the only tea estate in Kollam district, old British era tea factory, viewpoints, waterfalls, estate bungalow stay etc. But I’m struggling to find reliable, up-to-date details.

Has anyone here actually visited recently?

I’d like to know:

Is it genuinely worth travelling for, especially for a family holiday?

How is the scenery / overall experience compared to places like Munnar, Vagamon, Thenmala etc.?

Is the estate stay / bungalow accommodation good, clean, family-friendly?

How is the food there? Available onsite or do you need to arrange separately?

Is there enough to do for 1–2 days, or is it mainly a short photo stop?

How are the roads, accessibility, mobile signal, safety, especially with kids/older parents?

Best season to visit?

Also — where can I find reliable details/contact info/booking info about Ambanad Estate? Would really appreciate honest experiences and advice.
