Oh! and I said "december to march" trying to explain what I meant with "summer".. I know they're pretty different places..
Anyway, I'm new in this web.. and I won't post any other question or ask for advice.. I'm sorry to bother you all! I thought maybe you could help me to make up my mind!
Thank you all!
Please don't let the condescending replies from some posters get to you. If you want to see both places, you have every right to, regardless of whether others think your idea is ill-conceived.
There are so many different things to do in Uruguay and Peru, it's kind of difficult to give advice unless we know what sort of activities you are looking for on this trip. Are you looking for nightlife, cultural activities, historical features, or just a few months of relaxing and doing nothing? What sort of budget are you proposing, cheap, moderate, or expensive? Generally, the more specific you are with your questions, the better other members can help and give advice.
You can also check out our Wiki section, there is some great information to be gleaned from those pages:
So, stick around...there are lots of terrific people on this site.
lovelylau, don't be overly sensitive. Now that you've explained that you're based in Argentina then your question about two such completely different countries that are so far apart makes much more sense.
In my opinion don't consider Uruguay as a "real" trip. You simply take the ferry from Buenos Aires, no big deal. The express ferry takes about an hour, the regular ferry takes about 3 hours. It's such a normal trip that Argentinians and anyone else in Buenos Aires visit it as a day trip. To explore further, as mentioned above Uruguay is not a difficult destination... it's not very big and with few exceptions it's kinda boring and "normal." It's not a place that you have to research heavily or make complicated plans.
Since you don't have much travel experience it's a great place to start, just so you can get used to travelling. Think of it as a short get-away from home, that's all.
Peru is another matter entirely... it's a long way from your home and is chock full of MANY interesting historical, geological, cultural, etc. places of interest.
Another thing to consider... since you're going all the way to Peru then think about extending your trip into Colombia (my favourite South American country by far) and perhaps Ecuador or Bolivia too. You have lots of options in that part of South America.
