We like to think of marquees as puzzles with lots of pieces that fit together. Stretch tents are blank canvases, they look different from one rig to the next depending on how they are rigged and decorated.
It really does depend on which marquee or tent from which company to the pricing, it can go either way. Stretch tents can be a little more expensive at times. They do require a lot of expertise to rig, they can fit into many spaces and are aesthetically superior (in our opinion).
