The last scene filmed included the entire cast so they could all wrap the series on the same day.
When asked how he thought the series would end, series creator Justin Spitzer said, "I always had in the back of my mind that this series would end with Amy finally leaving Cloud 9, but then that ended up happening at the end of season 5 anyway, so that was moot. The only other thing I always had in mind was bringing back my daughter, who was in an interstitial in the pilot getting on the potty. I'd always said that whenever we wrapped up the series, I'd want her to be at whatever age she was on the potty in the finale."
Had the series continued, Carol's payout from Cloud 9 would have been much more significant and she would've bought Sandra and Jerry's apartment building as a power move. This idea was scrapped when the show was cancelled.
Amy's fake name tag says "Vangeline".
