I don't know anything about the tours specifically; we were there as part of a larger tour. I can say that it took us about an hour, from the time we walked down towards the tunnel area, until we exited at the Pool of Siloam. The tunnel itself was around 25-30 minutes, but we had to wait a little while for another group, plus there are stairs/walkways down to the point where you enter the tunnel and water itself. The City of David is basically what you walk through on the way to the tunnel, so you can definitely see both in the same morning, but again I'm not sure what the tour involves or how much time that would take. Note that you can definitely visit Hezekiah's Tunnel on your own without a tour, and I think you'd have time for that, but I don't know whether you're looking for a guided version or not.

you can but I would recommend wearing water sandals you have or an old pair of sneakers you can simply throw out.

You can buy tickets there; however, you will likely have a wait for the entrance time. You are better off buying tickets on line in advance...even that day so you know what time to arrive.

You cán just go without reservations. We walked there. There was no one else there.

I've walked Hezekiah's tunnel 3 times, and I would not recommend it for your husband. The width will be tight, but the height is a bigger problem. He will walk hunched over for the rest of the day after exiting the tunnel :-) !! If you're OK with going by yourself, then by all means do it, take some (flash) photos, and tell hi all about it. He might decide it is worth the discomfort and then you can go back together. It will have only cost you a few dollars extra that way. NOTE NOTE NOTE There are other tunnels at or associated with the City of David. 1) Hasmonean Aqueduct - a couple of miles southwest of CoD, near the Tayelet / Hass Promenade. The Promenade offers a spectacular view of Jerusalem, so it is worth a visit all by itself. But the Aqueduct is *very* tight and your husband will *not* fit, period. 2) The Western Wall Ascent / Drainage Tunnel - this is a ongoing excavation but it is open. It runs beneath the recently discovered "Pilgrim Road", which is itself being excavated and developed for tours. This tunnel is also very tight, and not a good "fit" for big people. Remember, these tunnels were not built for people to walk in, except for the workers who dug them.

We just paid for the tunnel separately
