We spent a night at St. Regis Cairo on a 35K cert topped up to 40K. Our original dates were 35 to 37K but Egypt Air flight schedule changes caused major modification to our itinerary. The night we stayed, the lowest retail rates on Marriott site, were over $800 BEFORE a 28% tax for Cairo hotels. So you are looking at an over $1000 night price tag.
Oh, the SNA cleared to a 2 bedrooms apartment. And we actually used both bedrooms because one person was suffering from having cold induced coughing.
