I have read many of the things on the forums and am narrowing stuff down but still am not sure whether Palace on Wheels or Royal Rajasthan vs. taking a driving tour with a company would be a best bet for 2 kids (aged 7 & 10). It will be about 10 night trip from Delhi to Rajasthan. Any suggestions or advise? I saw some reviews related to TGS tours as well. Any latest experiences?
