Ngaire, Marcie, and JoAnn, thanks! I was interested in whether Neferartari's tomb was the same that you just saw last time; I will try to book that tour. I can't tell if the overnight tour also stops there; doesn't say anything about it. Do you think it worthwhile to contact Regent or would they not know either?
Here's the two day tour description:
