Charlie Sheen
has had one beyond-crazy year -- so it's nice to see him capping it off by spending some quality time with his kids ... and ex-wife!

After a wild year of Tiger Blood, #WINNING, Goddesses and the loss of his job as Charlie Harper on "Two and a Half Men," Sheen is finally relaxing.

Charlie and ex Denise Richards have been posting photos sharing photos this week, showing them and children Lola and Sam and Denise's 6-month-old child Eloise in a mystery tropical paradise.

"Dinner with the family ... good times!" Denise posted on her WhoSay account, with Sheen adding "What's better than a modern family vacation!?! love spending winter break w/ @denise_richards & my kids!" on his own WhoSay.

It's great to see these two and all the kids getting along again after what has probably been a tough year.
