Following my telephone conversation with you yesterday, we have decided that we would prefer to go to Cambridge for our holiday rather than Birmingham. Of the hotels you suggested, we think that Red Inn would suit us best.
We should like to stay there for two nights from the 23rd, July. Our party will consist of two families, that is, two couples and three boys. Therefore, we shall require two double rooms and a 3-bedded room for the kids.
I enclose the completed booking form. and check to cover the deposit(押金) of ￡25 per person required at time of booking. I should be glad to receive confirmation of booking at your earliest convenience.
Yours sincerely,
Frank Simpson
