There is only one agent (Thomas Cook) in England that deals with your hotel.  I cannot book with them because I already have my flights reserved and only need the hotel.  The agent only reserves the hotel and flights together.  Do you understand?

Thank you to anyone who can help me.

Ýngiltere´de senin otelinle ilgilenen sadece bir acenta(Thomas Cook) var.  Onlardan rezervasyon yaptýramýyorum çünkü biletlerimi zaten rezerve ettim ve sadece otele ihtiyacým var.  Acenta sadece uçuþlarý ve otelleri beraber ayarlýyor.  Anlýyor musun?

Thank you both for your help.
