I wouldn't buy a lot of LBP. Around Beirut, most places will accept USD.
Some of the smaller places may not, so I guess it wouldn't hurt to have a little bit in your pocket.
Date on the image file says I took these in 2013, not 2014.
On the ramp at Rayak Air Base, looking southeast at the snow on the mountain.
Pigeon Rock, Bay Rock, etc
Different view:
If you like trains, Lebanon has an interesting train/railway history dating back to Ottoman times.
There is an old train station near Rayak that has some rolling stock and engines.
They were talking about making it a museum, but never got funding.
I don't know if you can still visit or not. It might be too far gone.
Google it.
Edit: For what it's worth, I stayed at the Radisson Blu. Pretty good place with 'controlled access'. Not too pricey. Good breakfast each morning. Within walking distance to the marina and several good restaurants.
