Exactly 51 years to the day since their last promotion from the second tier, a goalless home draw against Charlton saw the Bluebirds return to the top flight having led the npower Championship since November.
Hudson had been a key component of the team until ankle surgery brought his campaign to a premature end and he said: "This is the best moment of my career. I'd have loved to have been out there in a shirt but it didn't quite happen for me but that is football."
He added: "But I have been there in the dressing room right up until kick off of every game. I still spoke in the dressing room and I stay in there until the team go out and I try to add my bit if I can.
"It is the best dressing room I have been involved in, every player has worked their socks off this year, whether they've been involved or not."
After falling short at the play-off semi-final stage to eventual winners Reading last season, Cardiff manager Malky Mackay made a concerted effort to give his squad more depth.
The likes of Fraizer Campbell, Peter Whittingham, Nicky Maynard, Matthew Connolly and Heidar Helguson, as well as Hudson, were all missing from the starting line-up that earned a point last night.
And Hudson pinpointed that squad depth as a crucial element in the class of 2013's elevation to the top table of English football.
"The depth of the squad has helped us this year - that is what you need in this league," he said. "It is a gruelling season in the Championship and it gets harder every year. Anyone can beat anyone and people have said you'll need the highest points ever to stay in the league this season - it is so tough.
"We didn't quite have the depth last year but we added in the summer and again in January which helped us."
