Trip to Thorpe Park - London (2 day pass, 2 night stay) ?

I am trying to sell a trip to London (for 2 people) which I am unable to go on due to personal reasons. There is a hotel booked for 2 nights at The Holiday Inn, which cost £250 to book. Breakfast is included in the Hotel. The hotel is listed here: http://www.holidayinn.com/hotels/us/en/shepperton/lonsh/hoteldetail There is also a 2 day pass for Thorpe Park amusement park,worth around £90 (with included parking spaces.) The hotel is very close to the theme park and it was intended as a trip for the purpose of visiting it. It would be ideal for couples looking for a short break. It is booked for the next half term holidays, Wednesday the 6th, and Thursday the 7th but the hotel are willing to change the booking for up to 2 weeks either side. All tickets can be sent by e-mail.
