I would love to go on a saturday but most of the time that's impossible
I have a certain family member that I have to take out on saturdays. every saturday. forever.
So I go on sundays. yep! This is why I prefer 3+ day conventions, since I can take off Friday and go then too! And then I get at least one full day in
Going on sunday sucks if that's the last day. The convention shuts down early (usually around 5) and by around 3 people are already packing up and getting ready to go home. Plus you see lots of people carrying swag around that ran out on Saturday, and the majority of pictures are taken on saturday, and the masquerade happens on Saturday...
Yeah. Some conventions aren't worth going to if you can't go saturday
On the plus side! It's slower, so you can actually talk with the people at the booths, the deals are better (if they still have what you want in stock), and parking is easier.. and much cheaper to get.
So there ARE benefits to going sunday! It's just, if you have to pick one day, Saturday is often better lol.
