Hello!
Dumb Question: Your food ordering shops weren't through Red Quanta were they? (If so, I advise that you stop doing them until you have read the threads on this forum about that company.)
There are tons of travel-related shops. However, many/most will require that you do a few (quite a few?) lower-end shops with the company before you will be assigned. The experiences some folks have are tremendous. The world of mystery shopping is quite large. If you have not done so, check out the pinned posts in the "new shoppers" area on this forum. They will really increase your awareness about this industry and the possibilities for shoppers.
Hard work builds character and homework is good for your soul.
