What kind of breakfast do you have?
How much does it cost?
Is there a coffee machine in the room?
I cant answer you for the breakfast, but there is no coffee maker in the room. I highly suggest you check the temperature in Horley on the day and evenings of your stay. There is no AIr conditioning, again at least not in the room I had. We got lucky because it was nice at night so opening the window made it comfortable. However if you are staying during a time when temps are high you may not be so comfortable.
Accomodation rates can be based on including breakfast or plus breakfast - with early departurers many dont have time to eat at the hotel. When we have ate breakfast it was very good and nice choice.
Whilst there is not a coffee maker in the room - there is a kettle with tea coffee and milk so you can make a drink
Evening meals are fine - but to start your holuday a short stroll to ye olde five bells is a better experience - cant recommend the corner house highly enough for one night stays before holidays + they provide at cost car parking and will arrange transfers tk and from airport. We have used them for over 10 years - see my reviews
