“The team is fantastic! Tiana has been most patient and helpful with helping us to find the right date and room. We had a few last minute changes, but she was most accommodating and helped us to sort everything out. The gentleman on the day was wonderfully helpful too. We had a few hiccups with our tech but he kindly assisted and solved the issues for us. All-in-all, a great experience and we’d definitely come back to hold another event at the venue in the future! ”
