We had a simillar problem ... but with a different epilogue :-)
Hilda Toledano, the self-appointed daughter of King D.Carlos, was not allowed to set foot in Portugal during the dictatorship, due to her very leftist political opinions.
After the revolution, she came and installed herself at the Sheraton Hotel, the most expensive hotel in Lisbon at the time.
Apparently one can be a very leftist person, without abandonning the taste for luxury, even if it represented by a hotel who, in 1974/75, was supposed to be the H-Q of the CIA in Portugal.
When she was checking-out, she was presented with the bill.
"Send it to the Foundation of the House of Bragança" she said. "I am the Duchess of Bragança, so they will naturally pay it".
Naturally, they did not !
