Dear Stasya,
Rest assured i have taken all into account to make your shows pop up and stand out as always. I would suggest the Opera house stage on Friday afternoon for what you have planned. I'll see if i can squeeze Bunny Prince to make an appearance, if you want him, too. though his School Principal will be harder to convince than Augustin. What's it with Teachers and thinking they are more important than Global Politics anyway?
Back on Topic, If we go Opera House, the front Plaza would have the perfect quaint medieval building we could use as Popup store. My own Brand will open a shop soon in it, so it would be the perfect place to stage your Idea as i already own it. Not to mention it sticks out from the surrounding more 19th century buildings. Historical and eye catching, you'll love it, promise.
As for the Guests, i have a very long list anyway. My own Show will open on Monday, so I'll have time to organize for the Rest of the Week. If you need to get in touch during the Time, come visit my office at the Convention center, not as good a view as my Apartment but it does the job while on site.
Yours truly,
Princess Adelheid von Uburzis
