"a letter to the hotel making the arrangements and reservation" - my formal letter

Topic
You and your family are planning to spend a weekend at a seaside hotel.
Write a letter to the hotel making the arrangements. Let them know when you will be arriving and leaving, what type of rooms you would like and ask them how much the weekend will cost. Also enquire about activities and places of interest near the hotel

To whom it may concern,

I am writing this letter to make a reservation for next weekend, July 10th, 2010 and also ask for some information about this hotel.
My name is XXXXXXXXX XXXXXXX, I would like to reserve a room in your hotel for three nights. I will be arriving on the morning July 10th, 2011 with my wife and daughter. Thereupon I will be leaving on the afternoon July 13th, 2011. I would like to know the availability and price for a sea view double room with an additional single bed, safe box, mini bar, air conditioner and free internet access. I would also like to schedule some activities before this trip, it would be greatly appreciated if you could provide me with some information on the surrounding area in regards to restaurants, shopping centers, entertainments and other interesting places.

You can send me the above-mentioned information via fax, using the number XXXXXXXXXXXXX or email me at: XXXXXXXXXXXXX

Thanks in advance for your response.

Yours faithfully,
XXXXXX XXXXXXXXXXX.

Instead of Sir/Madam, try "To whom it may concern"

"I intend to reserve this hotel for three nights"
A bit too forceful and awkward, try
"I would like to reserve a room in your hotel for three nights"

"And will be leaving on afternoon July 13, 2011"
"And will be leaving on the afternoon July 13, 2011"

"I would like to know availability..."
"I would like to know the availability..."

air conditioned to air conditioner

"I want to schedule some activities in this trip"
"I would also like to schedule some activities for this trip, it would be greatly appreciated if you could provide me with some information on the surrounding area in regards to restaurants, shopping centers etc..."

Since you're writing a formal letter the closing should not be "Yours Faithfully" but rather something like
Regards,
Thank You,

I agree! That is really thoughtful, Martin. Thanks, I did not know how to express that...

And it is good to add the word "room"
... to reserve a room at this hotel for three nights.

Ali, you can practice by typing it again and trying to include these corrections. Do you have any questions about them?

Great job!
Now you have a run-on sentence to fix:
My name is XXXXXXXXX XXXXXXX, I would like to reserve a room in your hotel for three nights.
You can use a period:
My name is XXXXXXXXX XXXXXXX. I would like to reserve a room in your hotel for three nights.
or a conjunction:
My name is XXXXXXXXX XXXXXXX, and I would like to reserve a room in your hotel for three nights.

:-)

Thanks EF_Kevin for your help.

Dear Bob,
I am writing this letter to appreciate your amazing photos and all that you did for me in last holiday.

First of all, sorry for my delay. I had to write this letter 10 days ago. I was so busy and didn't have any time for it. I had to prepare myself for an exam. It was very difficult for me and I was studying 16 hours a day. Finally, I took the exam yesterday. Thereupon, I could check your letter and saw your photos. Those were wonderful and made me so happy. I didn't think you could do this. It will be a great memorial for me. Every time I see these photos, I will remember you and our friends.

Well, I would like to invite you and other friends to my house in Paris next summer. I have a little surprise for you. Please let me know when you could come here.

Best regards,
John.

This is very good! Maybe you spent a little too much time explaining why it took so long to respond, but... that is no big deal. You wrote this in a very accurate and eloquent way.
