Thanks - you're typo was snowballing and another poster then moved on to persuading and making people go to mass - that could only have ended badly!
Back to the original question - I would prefer an interdenominational service, as a catholic mass isn't going to float my episcopal boat.
From what I've heard, they offer both a Catholic Mass and a non-denominational Protestant service on Easter. Disney is very responsive and I'd be surprised if they didn't respond to passenger requests to the best of their ability.
