Do you have any advice for potential travellers?
If you are set on seeing all the cities and major attractions on this trip then go for it, but be aware that you will spend 50 hours of your trip on a coach. That is 3 days of being awake or 25% of the trip. Also be ready for the coach which may be from the 1970s and unfit for modern travel on India's very bumpy roads, making for many unconfortable hours. The landscapes outside the window are generally not that impressive i.e. not much to look out at. After a while a cow on the road isn't that interesting any more....
I have travelled a lot but first time in India. I'm quite streetwise, and I guarantee you people will try to pick-pocket you, so be very careful with valuables.
Also, I would suggest do Golden Triangle only as the coach travel is crazy for the rest of the trip, compare to amount of time "doing" stuff and exploring. And if you want to see tigers, then book privately as you might get a 4x4 instead of a truck, which enables you to get closer to the tigers. In the truck you will be looking at tigers with the 4x4s in the way as the 4x4s are allowed to, and are able to, get closer.
Our tour leader advised against having street food, and NONE of our tour got a dodgy stomach...so it was very good advice it seems.
Unless you really know what you are doing, listen to the tour leader's advice on what to spend your money on, in terms of expensive shopping for Jewellery, textiles etc.
Bring a plug for the sinks...
Learn how to say "no", "not interested" etc for the touts who hang around the tourist trail like vultures on a fresh carcasse. Unless of course you are a fan of utter tat, in which case you will love them.
Persuade your fellow travellers to skip the "midway" lunch stops, just get a snack. You will wait one hour for the worst food at UK prices.
Bring a good book, neck rest, tablet, music, cushion, or high strength sleeping tablets...the coach journeys are long...
