I am looking at some business class award flights on Qatar Airways, and I see an option that has a 3 hour 5 minute connection (this will be booked as a single ticket):

Arrive DOH @ 17:05 (5:05PM)
Depart DOH @ 20:10 (8:10PM)

I've never flown through DOH before, and am curious if this is enough time to visit the lounge to use the shower and grab some food? I am curious if this is peak time and the lounge will be packed?

If anyone has personal experience with a similar connection at DOH, I'd appreciate your comments!

Thanks.
