I just spent a few NMT and I found Audie but I'm conflicted as too take her or not, I'm struggling to leave her here but at the same time she should fit in with my town!
I've done that with a few villagers but I ended up taking them just in case, I'd rather have the problem of moving them out than regretting not taking them! There have definitely been villagers I've regretted not taking ;.; but all the ones I took "just in case" I've ended up really enjoying even if they're not permanent!
Take Audie!!! She doesn't have an amibo so chances of you finding her again are slimmer than the amount of people that don't press B in airplane cutscenes!
If you're not sure I think you might as well take her, you could eventually exchange her for a character you prefer. She should be really easy to trade haha ! Everybody loves her XD
I would take her if you like her. You can always move her out if you end up not wanting her on your island, but once you leave, if you regret it, you can't just go back and find her right away!
Audie has a really cute personality (imo), and her house is really nice. I'd invite her if you plan on doing some villager trading. If not, no shame to just leave her behind. No need to only invite those that are deemed popular, invite those you like!
