I just posted something like this a few weeks ago. Alt failure, IMC. Found a hole, got VMC, landed no issue. Never declared because I never thought it was nessecary. If I was stuck IMC, sure. Parade of fire trucks followed me to parking... tower's decision.
Declaring is no big deal... it is for our safety. I certainly would have, if I thought it nessecary.
Glad to know I'm not the only one getting alt failures in the clouds though...
