The Panama canal has been a bucket list trip for me for years and this one was priced right so I took it. Overall I had a great time. Going through the Panama canal was very well done with Panamanian official on board giving timely reports over the intercom as to what we were seeing.
Just keep in mind that the Star is an older ship and will not compare to the newer ones in the fleet. If you have that in mind your expectations should be in line.
I am not overly picky about food so the 3 star food on this ship was just fine for me. I never had any problems with the food just keep in mind it is not 5 star.
