This is already better than the last one I corrected for you, so this time I'm going to revise paragraph by paragraph to show you how to make the writing flow more smoothly and how to avoid repetitious sentence beginnings. 

Today I'm going to start a increidble trip, i'm going to go to Cinque Terre, in the Northwest of Italy. Two weeks ago, I have already booked a cheep hostel, and now I hope this hostel was similar than in the photographs I can see. I have never had problems with Internet books, but maybe, this was the first time.

Today I'm leaving on an incredible trip to Cinque Terre in the Northwest of Italy. Two weeks ago, I booked a room at a cheap hostel, but now I'm nervous that it will not be like the photographs their website promised. I have never had problems with booking through the internet* before, but there is always a first time.

Also, I have to my wife booked a special trip along the beauty villages of the region. We will must to give a special code to confirm our special trip when we do the checking.

Once my wife and I check in, we have to give a special code to confirm that we can take our extraordinary** trip through the beautiful villages of the region.

Last time we took a plane, we had some troubles, because we couldn't check in in the expensive hotel I had booked before, so we had to look at other room to stay over but this room was dirty and threatening. So, the first, I will do when I will arrive at the hotel, is to revise my room and my reservation. If I find out some mistake, I will say the receptionist before I check in.

*** The last time we flew somewhere, we got into some trouble because we couldn't check into the expensive hotel room we had booked beforehand. The only other option we found was dirty and threatening. This time, before checking in, I will review our room and reservation to ensure it is up to our standards.

My wife is worried about the flight because she don't enjoy when she has to catch a plane (I think she prefer take a ship because the last time she took one she was getting a tan for all the trip). Really, I think she must take some pill for his travel sickness but she prefer the alternative medicine.

My wife is worried about the trip because she hates**** flying. I suspect the real reason she doesn't like flying is because she'd rather be getting a tan while traveling by ship. She does get travel sickness, however, and despite my advice to take a pill for it, she insists on relying on alternative medicine.

I hope this was a unforgotten trip. I will write about this trip when I come back to my home.

I hope this will be an unforgettable trip. I will write about once I've come home.

*There is some debate about whether or not "internet" should be capitalized. Originally, it always was, but lately more and more respected publications have stopped capitalizing it. Right now, you can go either way as long as you're consistent. I tend not to capitalize it.

** I changed "special" to "extraordinary" to avoid using "special" twice. There are plenty of other words you could use, too.

*** I would put this paragraph second since it seems to be connected to your worries about the hostel.

**** We use "hate" in the U.S. *very* lightly to express a moderately strong dislike. I don't know if that's true in other English-speaking countries. We tend to be a bit hyperbolic around here. :)

Once again, great job! I hope you have a wonderful, safe trip. :)
