There are 2 codes that are giving large discounts currently. ANT24 and EL7. Both give free aifare which saved us $2K pp. The code reduced the rooms $1K pp and a free upgrade allowed us to go up several categories that saved another $1K pp. So it amounted to $4k pp or $8K savings for both of us. I am doing an Antarctic cruise but the Egyptian Pharaoas & Pymamids cruise using the code EL& gives a large discount as well.
