junket
in
Ulysses, by James Joyce

a trip taken for pleasure and paid for by someone else

meaning too rare to warrant focus:

Junket is most commonly used to describe an enjoyable trip taken by a public official that is paid for by the government or by a special interest group. It is also commonly used to reference trips taken by executives. Much more rarely, junket can reference any excursion taken for pleasure (regardless of how it is financed); or a dessert made of sweetened milk coagulated with rennet.
