Dear Mr. Samson, 

I would be so am very grateful if I have to have this a chance opportunity to go to attend the conference. and for that, For that reason I will work hard in order to write am putting a lot of effort into writing an excellent essay. the best essay possible.

Could May you please tell me in which part of Spain will be take place the conference where in Spain the conference is being held? It would be so kind of you to tell me, because I am looking forward to know in which place of Spain this conference will take place in order to look some information and be prepared in every case. I would like to research the conference location in order to prepare for the trip. As part of my preparations, also kindly provide information on the mode of transportation, the locations of housing for the competitors, and the required format of the essay. 

On the other hand, I would like to know which kind of transport it would be used. Could you send the information to me? I would be happy if you could tell me that, too. I think that going either by train or by plane would be a great idea.

If it’s not a trouble, could you tell me in which place will be the competitors living these days?
And finally, it would be very important for me if you could tell me if I need to have my essay hand-written or typed. In both cases I am perfectly capable of doing it.

Regards,

Isabel

     Dear Isabel, 
     I know this looks bad, but your formal letter writing exercise contains too many unnecessary words. If there are a certain minimum number of words that you are required to write, consider expanding your narrative with additional subjects. Formal or business letters need to be percise and very clear. They should omit "wordy" paragraphs/sentences. I'd recommend you think about additional information one would request in preparation for travel to a conference, such as money for housing and food, a schedule of events taking place during the conference, names of speakers or working groups, etcetera. 
     Regards,

     Dan
