Personally, tripping never bothered me much in ACNL. Other than a little animation it... really didn't do much. It didn't hurt my enjoyment of the game at all. I'm sorry it's upsetting you so much, but I really don't think it'll be as bad as you think it will be. I don't say that to dismiss your feelings, I say it because I know, from my experience (*pokes custom title*) I tend to get really worked up over certain changes, especially ones I wasn't expecting. I nearly had a full-on autistic meltdown when I read the game was going to be released without holidays. I thought there was NO WAY I'd be able to enjoy the game as much as I enjoyed ACNL because of it. But... then I played the game. And I'm enjoying it more than I ever enjoyed ACNL- and that's REALLY saying something. What felt like it could ruin the game for me turned out not to be a big deal for me at all, and I realized there was no reason to get as upset as I did. Would I have preferred the game with all the holidays already in? Sure. But I still enjoy it. And you may prefer the game without tripping... but I also think you may find it's not as bad as you're worried it'll be.
So, to be clear, when I say "I don't think it'll be so bad", I don't say it because I want to dismiss your feelings. I say it because I know I tend to get worked up over things that aren't as big a deal as I make them out to be and, when I do, it helps me to have someone say "It won't be so bad." and explain why. I hope this helps even just a little.
