You will still find that even in this day and age the shell scheme booth takes up a lot of floor area at many exhibitions and trade shows.
If you are looking to test the waters at a trade show then it makes sense to keep the expenses small and go for a small booth.
The venue will set up and take down any shell scheme structures, all built into the price of the floor area.
The ceiling grid allows a multitude of options for where to fix your lighting and there will be a name board area at the front for you to take advantage of to.
You just need to decide on the carpeting, which lighting fixtures, how to dress your walls and which of your companies products to display on the floor area.
The above image shows just how nice a simple shell scheme booth can look without huge financial outlay and hours of setup and take down work.
