We took a cab from the airport to Copacabana and got to see some of the favelas from the freeway . Rio 's infamous wealth gap is certainly well deserved . We went straight to our hostel , Che Lagarto , only to find out that we could n't check in until 2 pm .

Question: What may they have done until the could check into their room ?
