"Hi there David!
I firstly wanted to write and say THANK YOU so very much for coming all the way to Jimbour House and setting up (and supervising/training people) with the activities at our Wedding in October last year. I am an absolute slacker for not writing sooner (apologies) to tell you how much everyone loved your giant games. My grandmother was delighted to learn croquet and even Jim's (the groom) workmates got in on the action.
I had no idea how busy the day would be for me and I never actually got to meet you in person, but I heard so much from our guests and there are no words to express how much I appreciated your professionalism, flexibility and quality of experience - I would (and shall) recommend you to anyone who will listen!
I have attached some special photos from the day that make me smile every time I look at them.
Thank you is not enough, but I'm sending it as a start. You rock!"
