The context was about international visitors being there for up to a week which sounds reasonable. Once EU is open it seems easy to spend a solid 2-3 days at EU, 1-2 days across Studios and Islands and then finish it off at VB. Remaining time hitting up all the favorites until the return home.
International visitors could definitely spend a week to the most out of their visit and you could bet that Uni is working on those kind of vacation packages. It might be hard to sell a week long vacation now but one EU opens it'll be selling itself.
I think if it's priced well enough, even if they go off property for a day or two during that week, they'll still stay at a Universal hotel all week so the company still wins. It would be the reverse of people staying at Disney and visiting Universal for a day or two like they do now.
