Based on reading people's posts on here, I know a handful of posters who's involved in this program. I also performed it myself for the first time last week.
From what I understand, the round of shops were to be done the same day. As to obtaining an exception to split the days? I'm not sure, but you can always inquire with the scheduler / coordinator; I'd say he's great to work with as he's responsive and easy to get a hold of.
What to expect? If you've done fast food, fast casual, dine-in, bar and retails shops for other MSC's, it's no different. Just read your guidelines as they do look for specific things, as I believe the client is the actually the airport, not the establishments themselves (correct me if I'm misinterpreting this y'all!).
Do I think it's worth it? The base pay per shop is $11.50 + reimbursements for the specific locations + they cover a fixed $ amount for parking expenses. Combined with other airport shops, I'd say it's a great project to have under your belt for what it entails. Plus, this will likely cover your breakfast and lunch for that morning (through required purchases, that are reimbursed).
I must say this though, every shop in the project required very, very detailed narratives. With that being said, the turnaround time and expectations are reasonable for what it pays and the opportunities it may open. Of course, YMMV, as your projects greatly depend on the airport that's in your area.
