Ima goes to the opera in Munich: another mystery

Excerpts from Ima Hogg's 1907 travel journal of her first trip to Europe:

Aug. 19. Monday. Munich. Hotel Linfelder [She went out by herself to pick up opera tickets she had ordered from London.]

Out looking--got lost--having left my dear old Baedecker somewhere--reached hotel 3:30 P.M. tired hot & hungry....

Aug. 21^st Wednesday Munich.

Four o’clock Tristan & Isolde! Started from hotel in a carriage at 3:30 in plenty of time...

[She described the opera in great critical detail. Was she alone?]

Had dinner between 2^nd and 3^rd Acts....

Came home decided on leaving out Vienna & staying for [Wagner's Ring] Cycle --if my ticket could be redeemed.

Thursday Munich. [Aug. 22]

Ticket redeemed, place engaged at Musicians Pension where Mrs. [name left blank] from Houston is staying & she, too, goes to the opera.... 

Ima bade farewell to her travel companions (a tour group mostly from Texas) and moved into a pension, where she stayed for nine days, going to the opera--and doing what else? Hmmm.
