Hi @oscarveratech,
If you already have expertise with wifi network design, go ahead with one of the options I mentioned, otherwise, the ideal is to find a partner company, because speaking of high-density environments, the ideal is to carry out a study that is as close as possible to the scenario desired, because this type of environment usually has several complicating factors. For you to have an idea, even the type of business can influence.
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
Please, if this post was useful, leave your kudos and mark it as solved.
