The Delhi-Jaipur highway route is simply the best road-track I've driven on till date. Driving 3-4 hrs at a stretch at over a 100 kmph is a great experience. Halfway on the route, lies the RTDC Midway , providing a perfect "midway" refreshment point.
There are a couple of things Jaipur is awesome at: forts, good food, colorful clothes & handicrafts and a few at which it sucks: traffic in the old city for one - landed up just in time for the pre-diwali rush in the ramparts of the old city, just to be swarmed by the crazy crowd...
The city palace is certainly one of the most colorful forts I've ever seen till date, perhaps because the royal family still live there (Not as magnificent as the ones in Udaipur, but still a sight by itself). The Amer fort is , of course, impressive, particularly when you first come upon it…the sheer size and its location add to its gravitas. Nahargarh and Jaigarh, which adjoin Amer are worth a visit as well, and are a good uphill drive. The view from Jaigarh fort of the city is certainly worth catching.
Choki Dhani, which lies on the outskirts of Jaipur, is perhaps the best Indian theme park (if you can call it that) I've seen. The ambience at night is just awesome - the camel and elephant rides, the village carnival atmosphere, the amazing food - its just wonderful. A must visit.
We stayed at this really nice hotel called Pearl palace. Extremely good value for money, really neatly laid out and with impressive interior décor. Its seems to be the favorite haunt of foreign tourists, hardly saw any Indians there. But a definite night stop for any visiting backpacker.
