Second draft of the Formal Letter

Dear Sir/Madam,

I am writing to you because I am very interested in the holiday 'Antartic Cruise', and I would like you to give me some information I need to know about this fantastic trip.

First of all, I am going to go with three friends, so I was wondering if you could tell me the price for four passengers, what it includes and when the best time to travel is.

Secondly, in the magazine advertisement it is not clear what kind of accommodation is available in the cruise, so could you give me the options of the different types of rooms? I would like to reserve 4 rooms, if possible.

Thirdly, I am a vegetarian and I would be grateful if you could include a special menu with vegetarian food, unless there is only one unchangeable choice.

Finally, it is the first time I am going to travel on a cruise, so could you please tell me if the safety of this trip can be guaranteed?

I look forward to hearing from you.

Yours faithfully,

Paola Gutiérrez
