Costs of playing paintball are covered here:

Another cost factor for the scenario or for any other events across the country are travel
& accommodation costs. Camping can be free but not always available and you may not feel like sleeping in a tent due to weather or you like your cosy bed & shower. Some people are in the extremes of the uk and either fly or drive hundreds of miles for one game. These costs dwarf the actual cost of playing.
Cost will be a factor in keeping some people away.
But there is nothing that can be done about it - cut prices and sites will make losses.
The cost of punter paintball is the right price to run a paintball game, provide the right facilities and give a good day out to the customer - when they go home happy then they may return, and people do return to sites as casual players. If they want to play more they work their way onto buying gear and paying less for paint, they can either save some cash by paying walkon prices, using the same paint quantity as punters and put the balance to equipment. Add a newbie friendly site that provides rentals to walkons and you have the stepping stone to allow players to gradually progress from punter to own gunner walkon.
It would be nice to have more money and for the things you spend it on to be cheaper, but that's not life.
Paintball is much cheaper then in its early days, by all reports its in a decline on the tournament circuit, it would probably be news for paintball site owners if I said they were booming, but they are attracting customers. If they charge the right price and keep their sites fresh then they can remain in business.
Every fortnight for most of the year is a lot of paintball. It's not only the cost that will stop people from doing this, there are other life commitments and other hobbies that take people's time.
For the tournament side of paintball there will be this kind of commitment, which will have had an affect. People won't be able to always be able to commit the time and money to regularly practice and compete, with walkons and scenarios people can make less of a commitment and play as much as they can afford or put the time in.
The argument of paintball being too expensive and stopping potential players is often heard, it's similar to all those potential professional footballers in pubs who hurt their leg once, and that's the only reason they are not now making millions.
Paintball is affordable to play once for anyone with some disposable cash. They can then decide if they are interested and then see if they can balance their income with expenses and other life needs then see if they can fit in paintball.
Being a professional paintballer is also available to people with a bit of talent - but it again takes some balancing to do, including making the commitment to take care of themselves, warming up to prevent injury, making other sacrifices and not getting hammered the night before a game
