[Wikimania-l] Bauen hotel: extended stays possible?

[Roan Kattouw]

Because of airline schedules and prices, it would be convenient for me
to fly into Buenos Aires on the 23rd of August and fly out on the
29th. However, the "Date(s) of stay" field on the registration form
only allows me to check 24-28. It's unclear whether the checkbox for
e.g. the 25th means the night between the 24th and the 25th, the night
between the 25th and the 26th, or just the 25th (can anyone clarify
this?), but either way I'm one or two nights short. Could the local
team please advise as to how to arrange for additional nights at the
Bauen hotel?
