Possibly £22.75 per room per night with Topcashback currently offering 9%.
Seems to be availability for most Fridays/Saturdays over the next couple of months.
Quite a handy hotel if visiting Legoland, Thorpe Park or Chessingtons.
No breakfast included for this price, but there is unlimited tea/coffee and free wifi.
There is also an indoor swimming pool, jacuzzi and sauna.
The rooms are really nice with flat screen tvs and modern decor, gets good reviews here:http://www.laterooms.com/en/hotel-reviews/86792_de-vere-venues-horsley-park-east-horsley-guildford-leatherhead.aspx
