The problem with WiFi is your are at the mercy of the WiFi provider. Some have limited bandwidth which means the more people using it the slower the speeds will be. For example on resort we stay in the WiFi is really slow from about 4PM to 7PM. It's nearly impossible to watch any streaming type program like a TV show or Sports event.
Another problem is some provider will throttle the speeds of heavy users to prevent one person from using up all of the bandwidth.
It is getting better but a satellite dish is the best way to go for now.
