Not for me. All of mine have been very challenging and have required that I spend gems just to expedite production of t-shirts and other such items. I have to start working on my Boardwalk the second my preview is available and check constantly to keep my factories going (I've expanded most of my factories to at least 5-6+ slots). Right now they're driving me crazy with the Hot Dogs and Robo-Pals orders. It takes a lot of time to make everything for the hot dogs. I have to create an average of 10 stoves to make most of my items (hot dogs, cheese, balls, etc.), 12+ shirts (to make rugs and dolls), and a ton of other stuff. It's really impossible without spending my gems and still being on the app constantly, literally staying awake most of the night (talk about an addiction, right?). I try to create and save up what I can also, while still filling my other building orders. <sigh>
So much work, so little time. I didn't expect it to be easy as I leveled up, but I do expect it to be reasonably achievable.
