Lindsay Lohan & Family -- FELIZ NO DAD

Lindsay Lohan and her family celebrated an arrest-free Christmas in New York -- but one family member was conspicuously absent ... you get three guesses.

While Michael Lohan celebrated the holiday in Florida with his on-again-off-again-on-again GF (now fiancee) Kate Major, the rest of the Lohan family got festive at Dina's house in Long Island -- including Lindsay's grandma and siblings Ali, Cody, and Michael Jr.

We're told other family and friends were present as well ... and it was actually fun -- drama free, as they gorged themselves on a massive Italian feast.

As for the tree -- we're told money did NOT grow on it.
