Hi, I'm from Rio and I can give you some tips.
If you want to stay at Copacabana Palace, check the website first,
www.copacabanapalace.com.br. It's one of the oldest and it's the fanciest hotel in Rio. But be prepared, a hotel room is very expensive. A room with the view from the Ocean won't cost less than 553 €.
Around Rio you could visit these cities:
1) Beaches
- Búzios (2,5 hours drive East from Rio) - is the typical fisherman village, with good nightlife, cozy hotels and hostals, beautiful beaches. Website with info in English

- Angra dos Reis (3 hours drive West from Rio) - it's more of a boat-island place, you won't find beautiful beaches on the continent, but if you rent a boat, you'll discover very beautfil unhabitated islands and it's perfect for diving. Website with info in English
http://www.angra-dos-reis.com/ingles/index.htm
- Paraty (next city West from Angra dos Reis) - fisherman's village, built in colonial style dated from the 18 th century. Not many beautiful beaches, but you can always take a boat or walk to very beautiful places. Website
www.paraty.com.br (it has info in English).
2) Mountains
If you want to check different landscapes than beaches you can try some cities in the mountains like
- Petrópolis - 65 km from Rio, it's worth for a day trip. I didn't find a website in English, but you can check info about the city at wikpedia
http://en.wikipedia.org/wiki/Petropolis.
3) Nightlife - there aren't great clubs in Rio, but in November, unofficial Summer has already begun, and you can check for special events that happen during the high season. I would recommend you to go to 00 (Zero zero) for house music, which is an open-air club. Check for these special parties: Delírio, Rio E-music Festival, Groove Attack, Chemical Music Festival, B.I.T.C.H. Party, all are excellent events and you have a good chance of one of them happening at the time you'll be here.
At "Circo Voador" there are some good eletronic music events, but you have to check the agenda for the "Circo Eletrônico" event.
If you need more info, pm me and I'll be happy to help you.
