One place I have always wanted to visit in India [with the exception of the Taj Mahal gardens] is the Golden Temple. Is there a problem with being in a wheelchair? I can cover my head without a problem, but how does one show respect with wheels? Normally one would remove the shoes and wash ones feet. Well, there is also a problem with sitting on the floor if we have the possibility of eating a meal there as well. 
This Link from disabilityindia.org states that the temple itself has deputed volunteers for persons with disability.
Hope this helps.
IIRC from my visit there should be no problems in entering the Harmandir Sahib in a wheelchair. The temple area is mostly at ground level, and I’m sure people would be very helpful if you needed assistance. I would worry more about getting to the temple.
It would probably be a bit of a hassle to spend a night or two at the temple premises as many tourists do: Western tourists sleep in a rather small dormatory with shared bath/toilet facilities (and a turbaned Sikh with a spear to guard the room).
Wonderful link, and excellent information - I had not heard of the small hostel for visitors.
We would be staying in a hotel and not trying to spend the night there, just visiting to expand my exposure to a whole new religious culture. We are going to be trying to get there while I can still do some very slight gimping on crutches to get into locations. If I can clean my feet and transfer into one of the temples chairs and have the driver lock my chair into the car that would be perfect. I was willing to try to gimp in on crutches but I really can not sit on a floor and didn’t want to be seen as being rude on insisting on not sitting on the floor. [hell, I have days when getting out of bed can be problematic…]
I know the Taj Mahal is set up for handicapped, I have seen stock footage in travel shows with the occasional person in a wheelchair in the background. I have a fairly heavy invacare chair that I use for travelling as it is less twitchy than my lighter regular chair, and folding crutches as well =)
The tentative itinerary will so far include the Golden Temple up north in the Punjab near the Pakistan border, the Taj Mahal in Uttar Pradesh, and somewhere along the way I want to do the very touristy ride on an elephant =) We were thinking since they are both in the north of India, we could fly into Jaipur and do the Taj Mahal first, then head up to the Punjab and see the Golden Temple, and head back with some light tourism along the way each direction and have a very nice 2 weeks in November without hitting any major festivals. We were figuring to go through one of the recommended tourism agencies and getting a car and driver. We really only tend to travel with one suitcase and a backpack between us so there should be plenty of space to stash the wheelchair.
Would my normal travel wear of a salwar kammez be seen as rude[I am glowingly pasty white and anglo saxon]? I just tend to like being comfortable…
People will probably look at you funny if you wear salwar, but nobody will be offended. It’s not sacred or anything.
Car + driver is probably the best way to go. The trains are wonderful, but probably a lot less so with a wheelchair.
I don’t think anyone will even notice that you are wearing salwar kameez except, perhaps, to compliment you for it. And comfortable is definitely the way to go!
As for festivals there are at least 3 public holidays in November - and who knows how many local festivals. I think the only time where you can be more or less certain of not running into a festival somewhere is the period from late December to mid-January.
If you’re in Jaipur do not - repeat, do NOT - miss Jaisalmer. It’s utterly amazing.
It’s quite far away from Jaipur, though. Probably a day or so each way. I’ll recommend Udaipur over Jaipur any day, by the way (I consider Jaipur HUGELY overrated). And when you’re in Agra (for the Taj Mahal) you could look into seeing Mathura and Vrindaban which are quite close to Agra. Lovely places that see a lot less tourists than Agra or the popular places in Rajahstan.
But still closer than Agra.
So do I. The elephant ride to the fort was fun, but it didn’t really have much else going for it.
