How do you define destination?

I did a week-long trip where I never spent more than 24 hours anywhere, though I did sleep in hotels twice along the way.
JFK-DOH (~10 hours on the ground; hotel)
DOH-BKK (~12 hours on the ground; hotel)
BKK-RGN-SIN-PER (17 hours on the ground 6a-11p)
PER-JNB (12 hours on the ground (6a-6p)
JNB-IST (8 hours on the ground (8a-4p)
IST-JFK

But that was essentially 7 days "in transit" from my apartment in NYC to that same apartment. So add 90-120 minutes or so at either end for the train to/from JFK.

I did another, similar trip of JFK-HEL-TLL//overnight//TLL-RIX//overnight//RIX-VNO//overnight//VNO-HEL//overnight//HEL-BHX(or MAN)-JFK.

Another trip was ARN-TXL//overnight//TXL-MUC-LJU//overnight//LJU-SKP//overnight//SKP-IST (all that was a single, one-way award from United ). Eventually did IST-MUC-JFK with a 23:55 connection in MUC to get home.

And then there was the BWI-IAH-SEA-IAH-BWI-IAH-SEA-IAH-BWI-IAH-SEA-IAH-NRT trip. Three consecutive SEA-IAH redeyes is not recommended. Best part was the same FAs on nights 2 & 3; the one was VERY confused when she saw me again.
