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 ?
Answer: They decided to visit Copacabana to see some of the favelas from the freeway .None of the above choices .They enjoyed some local tourist attractions that were near the establishment they had reservations at .Nothing at all , they sat in the lobby until   2 PM .
