I will be on the Sinai Experience tour that leaves April 17. I see that we arrive back in Cairo on the following Saturday. Will we be back in time to attend the Whirling Dervishes presentation at the El Ghuri Mausoleum - Cultural Centre? I think it begins at 8:30 or 9 pm. I would VERY much like to attend it if possible. Perhaps other members of the tour would as well.
