Pondicherry Trip- where to stay and what to visit there, Road route from bangalore to pondicherry.?

I visited Pondi couple of times,

Here are some tips for a good stay:

Park Guest House (Run by Arobindo Ashram). Excelent location, have a nice garden, airy rooms, spartan arrangement, no luxury, no alchohol. the location is worth sacrificing the luxury.

The Promenade Pondicherry (a 5 star Luxury hotel run by the HiDesign group).
A standard Luxury hotel with good location. I didn't find anything special about it.

Le Dupleix, this is the hotel in the same building where Robert Dupleix stayed, you can try that out and will get an idea about Colonial Luxury.

Patricia's Guest house. A 100 years old Frech Villa, own by a lady named Patricia, she has couple of ac rooms for guests, this place is exquisitely decorated with colonial art. You will get an absolute piece of colonial living of the French. You have to call and book the rooms.

Having dinner at Rendezvous is a must for Classic French, authentic Creole & Coastal Indian cuisine.

If u plan a trip to pondi, I am driving down from Bangalore on the 15th of Oct. and I travel alone, Business trip.
If u would like to join me, It would be a pleasurable experience.
I am driving an SUV, I usually stay at Patricias, Le Perrie, or at the Ashram.
I am planning a 4 day trip.
IM me and we can plan up

Personally can only help you this much that you could try out this site www.oktatabyebye.com. Being a travel enthusiast I am a member on this travel community. Recently they have introduced a Travel Maps and Driving directions section. I am confident that you might find your answer there. I recently did this trip to Haridwar and used a direction posted by another member, it was good and helpful. There are member contributed Travelogues and features on place that give good ideas on what to see etc. plus there are again real member submitted hotel reviews where you might find pondicherry hotels. All I could help with really, so hope you find your answers there. Good luck and have a good trip.
