Larger events, when they are done outdoors, require a good way to cover stations from the sun and potential rain. Notice when you go to festivals that almost every booth has a large canopy tent above each and every stand. This is the perfect example of what you will need for events as well. It should be a stand-alone tent with sufficient anchoring to the ground.
There are plenty of options. You could go to one of the major markets and buy one. Be careful with that one though. Often, there are cheap versions but they tend to break down easily or they get swiftly blown away by moderate winds. Others may be costly but not as effective as you would think. Somewhere in the bunch is the right tent, but which is it?
Instead of dealing with all of this nonsense, just go ahead and look into getting an event tent rental. One thing is for sure and that is the tent you will be renting is definitely of the quality you would need for any event, hence the name. The fact that you must rent the tent means that others have used it before and it works.
Then, if you still want to buy one, at least you have a real idea of what the right one will be and what it will feel like. The better tents are more expensive so you will do well to just rent if you only have one or two events to prepare for. If you are a professional event provider, you will need to actually invest in the tents and not just rent them.
Get your event on focus. Don’t be concerned about the tent or other issues which can be contracted out. Focus on the details which really matter in the end.
