WWE is planning WrestleMania 37 as a two-night event. The pro wrestling world will be focused on Tampa for April 10th and 11th, but the company wants to plan even more action in the area.
The company typically holds SmackDown and RAW from the WrestleMania host city. They might have some issues this time around as reported by the Wrestling Observer Newsletter
The company cannot use Tropicana Field because the stadium will be taken for Major League Baseball. There is a possibility that they could use the Amalie Arena which was set to host RAW, SmackDown, and the WWE Hall of Fame last year. That is not a lock as of this writing.
It is also unknown if WWE will allow live fans into those televised events, or whether they will put up the ThunderDome once again. A lot of questions are left to be answered at this point, but the Tampa Bay Lighting will be out of town after April 4th.
