Narrative:
A mrlin 4 arrival (STAR) into fll. Clearance was given to cross mrlin intersection at 8000 ft and tritn intersection at 250 KTS. Clearance given to us by ATC was given too late to make the altitude restr at mrlin. We programmed the FMC for tritn at 8000 ft in error. Passing through 16000 ft; we asked ATC about making mrlin at 8000 ft and they asked if we would make the restr. We told ATC we were expecting tritn at 8000 ft. Then 5 mi prior to mrlin we told ATC we would accept a vector if there was a traffic conflict. ATC advised that there was no traffic conflict. Controller checked with approach control and added that there was no traffic and did not issue us a vector. ATC then changed clearance to 'descend to 8000 ft.' previous day was 13 hour duty day; 5 legs; 7 hours 7 min flight time. Rest time ws legal but barely 9 hours at hotel. Long crew duty day combined with short overnight into early departure and early wake-up for duty contributed to fatigue factor.

Title: FLT CREW OF B757 CITES FATIGUE AND INADEQUATE REST AS A FACTOR IN THEIR FAILURE TO MEET A XING RESTR IMPOSED BY ATC AND A STAR ARR AT FLL.
Narrative: A MRLIN 4 ARR (STAR) INTO FLL. CLRNC WAS GIVEN TO CROSS MRLIN INTXN AT 8000 FT AND TRITN INTXN AT 250 KTS. CLRNC GIVEN TO US BY ATC WAS GIVEN TOO LATE TO MAKE THE ALT RESTR AT MRLIN. WE PROGRAMMED THE FMC FOR TRITN AT 8000 FT IN ERROR. PASSING THROUGH 16000 FT; WE ASKED ATC ABOUT MAKING MRLIN AT 8000 FT AND THEY ASKED IF WE WOULD MAKE THE RESTR. WE TOLD ATC WE WERE EXPECTING TRITN AT 8000 FT. THEN 5 MI PRIOR TO MRLIN WE TOLD ATC WE WOULD ACCEPT A VECTOR IF THERE WAS A TFC CONFLICT. ATC ADVISED THAT THERE WAS NO TFC CONFLICT. CTLR CHKED WITH APCH CTL AND ADDED THAT THERE WAS NO TFC AND DID NOT ISSUE US A VECTOR. ATC THEN CHANGED CLRNC TO 'DSND TO 8000 FT.' PREVIOUS DAY WAS 13 HR DUTY DAY; 5 LEGS; 7 HRS 7 MIN FLT TIME. REST TIME WS LEGAL BUT BARELY 9 HRS AT HOTEL. LONG CREW DUTY DAY COMBINED WITH SHORT OVERNIGHT INTO EARLY DEP AND EARLY WAKE-UP FOR DUTY CONTRIBUTED TO FATIGUE FACTOR.
