Me and family planning for a trip to Alleppey. I would like to know which is the best resort to stay at Alleppey. We are 4 people.
Closer to Kochi, you could consider Kondai Lips which is in Alleppey District.Ponnamda could be a choice too.

I prefer lake side resort
Hi Kooljojo, I would suggest you Emerald Isle - Home stay. It is fantastic location on the lake front with some amazing services. I can help you reserve this at price of INR 5400 per room / per night Let me know if this interests you.
You can consider these budget hotels at Alleppey:
Emerald Isle Heritage Home
Shaanthitheeram Lakeside Heritage Resort
Raheem Residency
Tharakan Heritage Resort
All of these are nice hotels and suitable for family stay :)

If you are travelling with Kids, these suggested hotels may not live to your expectations as they do not offer much activity for children. Children would require activity and unfortunately though the services of these mentioned home stays is great but do not really offer the freedom of exploring, which Kids would like, Mararikulam would be better choice for Children specially Marari Beach Resort. However the price would be much higher.
If you are adults then it makes complete sense as these are absolutely noise free zones away from the bust life in the cities.
