Both segments (AMS-CDG and CDG-NAP) are available separately at Skyteam rate (20,000 for AMS-CDG and 25,000 for CDG-NAP, 24 to 26 March 2006). It might be worth giving FB a call next week to see if they can price the combined award at official 'Europe 1 to Europe 2' rate (25K).
Be ready to pay huge taxes (more than 130€. KLM prices this route with 160€ in taxes and reservation fees...

)
On a side note, the 12:40 inbound flight from NAP will definitely shorten the weekend.
