Hello folks:

I grabbed a J ticket to travel from CGK to SEA on QR. My flights are QR 955 and 719. Sadly, 955 does not offer QSuites, but I hope 719 still does.
Anyway, I have a 2.5 hour layover at DOH. I have never flown QR before and am looking forward to checking out their Al Mourjan lounge(s). I know that one lounge is in the south and the Garden is in the North. My questions:
1. Given my flight schedule, which lounge should I visit for the greatest convenience?
2. I believe checking out both lounges is gonna be difficult, with only 2.5 hours to play with. Anyway, which lounge is nicer?
3. Do they serve the same food?
4. Is there hand baggage storage at both lounges?
5. Is the shower room worth checking out?

Thank you very much!!!
