I'm curious about this, but not specifically for Trader Sams, but the monorail resorts in general. I thought you need a reservation to go but I've seen vloggers go without them (or I'm assuming since they're going to Tambu but not a restaurant, for example). Because we would really like to go to the monorail resorts during our trip, and we're willing to make a reservation, but we don't want to if it's not actually necessary.
