Europe or America?

Europe is safer.

Around $4000 in what kind/nation money?
That ain't much. Initial plane fare costs like crazy.

good luck.

Europe is a better cross section view of the world.

Is that US$4000?

For everything?...flights,insurance,visas, plus accommodation,local transport,food and activities?

Where exactly are you flying from?

-Norway (The Northern Lights)

Norway is very expensive even by general European standards. To have any chance of seeing the Northern Lights you will need to go to the north of the country, and it is a very long journey. There is absolutely no guarantee of seeing the Northern Lights. It's something that one takes a chance on seeing if one happens to be in the area anyway, but going hundreds of miles out of your way with only a slight chance of seeing them is a pointless idea, especially if you are short of money.

Your destinations in Europe are very widely spread out, and not all of them are in Europe anyway. Sweden is a large country. Where in Sweden does your friend live? Norway and Sweden are next to each other, as are France and Spain. Where in France? I assume you mean Paris, for the Eiffel Tower and Catacombs. But France is a long way from Scandinavia, and the only practical way to go from Sweden to France is by air. Then again, where in Spain is your friend? Perhaps he/she could meet you in France if your only objective is to meet your friend.

Morocco is in Africa. Why are you thinking of going all the way to Casablanca? Because of the movie? Then from Morocco to Greece is a very long way and you would need to fly. I have no idea whether there are direct flights.

There are no ferries from Greece to Israel. You would again have to fly.

Tips and suggestions will come when you have done a lot more homework. At the moment it is just a random list of places that you appear to have read or heard about. It’s not an itinerary.

I can’t comment on the America suggestions. I had never heard of either the Oregon Vortex or the Winchester Mystery House, so I had a look on Google It is a completely ridiculous idea to travel halfway around the world to see two “haunted houses”. These are things that you might take the time to see if you are in the area. I can’t imagine anyone travelling all the way from Asia (wherever in Asia you are) just for that. OK, we all have different interests. I like steam railways. But I wouldn’t go thousands of miles just to spend an hour riding on a steam railway.

Since you say you are short of money you need to scale back. How long is “some months”? And I am also asking, what kind of dollars? And does it include your flights from Asia? Moving around as much as you want to do will cost a huge amount of money.

Op, you need to prioritise your dreams.

people should think about what they want to gain from their trips.

It is US$4000, and it is meant for Visas, Accommodations, Local transport, Food and Activities. Plane tickets are something else...

Now, allow me to say Thanks for the always fast, always great answers!
Even with the lack of information, I actually get what I was asking for.
Which is....Europe is safer, but would be more expensive.

Hah, as much as it pains me to say. Since the odds of going to Europe are more against me and I got a promise to fulfill in June in Cuba. I guess I will be heading down the America route this time.

And now that I've decided on going to the America route.
Time to do the homework...

Slow down reagen. Your 'America Route' as shown:

-USA (The Oregon Vortex, Winchester Mystery House)
-Mexico (Zihuatanejo and some ruins)
-Colombia? (Got a friend there)
-Peru (Machu Pichu)
-Bolivia (Salar Del Ulyuni)
-Brazil? (My friend, if we ain't meeting in Colombia, it'll be in Brazil)
-Cayman Island and Cuba for 2 weeks

Is not going to happen on $4000. Even if you pay for all flights between countries outside of your $4k, it isn't going to happen. You might manage the Cayman islands and Cuba for 2 weeks on your $4k and not much else. You say nothing about total time you plan for this but if you use $100 per day as a ballpark average including only local transport within a country, you would have enough for 40 days. In the USA and the Cayman islands you would be lucky to get by on that amount per day.

Yep.
After looking at a lot of prices and flights, it seems I'm being too naive on this. (My God, as "Close" as I think places is, flights are damn expensive!!) Even though, if things goes well I might be able to get an extra $1000 to spend on things for the trip. As you all say, I don't think I might be able to do much.

Well, cuts are to be made.
At this rate, I wonder if I may at least make it to Cancun, Mexico to go and see the Chichen Itza in Yucatan, spend a day or two around because I heard it is huge. And then go across to Cuba for 10 days, and lastly a few days in the Caymans (I still might have to cross Cayman off). What do you guys think?
Or might I be able to add more South American country? (More Carribean Islands is probably bad....)
