I'm probably going to be in the minority here, but I'm hoping WrestleMania one day becomes a 2 day event. 4 hours on Saturday, 4 hours on Sunday, 2 hours each day for the pre-show, and 1 hour each for the post show. I would treat it like an award show, complete with a red carpet entrance for celebrities and special guests.
Day 1
Intercontinental Championship Title match
United States Championship Title match
Raw Tag Team Championship Title match
Smackdown Tag Team Championship Title match
Andre the Giant Memorial Battle Royal
10 Woman Tag Team match
Celebrity match
Day 2
WWE Universal Championship Title match
WWE World Championship Title match
Raw Women's Championship Title match
Smackdown Women's Championship Title match
Undertaker match
Brock Lesnar match
Main Attraction match
Think about the back to back attendance records. Think about how fun that entire week would be for that city.
If it too much for you, just watch it at your convenience.
