Oh, man too bad. At least you got some shots of your trip.
I have a "rugged" camera- waterproof, dust proof, drop-able, the whole shebang, camera. Among it's adventures were several hot spring trips. What I was to find out later is that fine residue from dried mineral water gets into small places.
Oh well, it didn't promise that on the box.
Blasting it with canned air helped a bit.
