The couple will tie the knot on Friday, December 30 in front of more than 250 family and friends at the hotel.
Following the nuptials, the Dubliner and his bride will enjoy their first night as husband and wife in the Georgian manor home’s exquisite presidential suite.
Guests will be wined and dined at a marquee set up in the estate grounds as the hotel’s restaurant can only accommodate 95 people at a time.
Guests are expected to party into the early hours of New Year’s Eve before departing the estate to ring in 2017.
Several famous faces are expected to attend the wedding, including the 32-year-old’s fellow All-Ireland winners like captain Stephen Cluxton and his wife, Joanne, and Paul Flynn with his girlfriend, Fiona Hudson.
Bernard’s former teammate Ross McConnell is expected to act as best man at the bash, while his older brother Alan, who has won three All-Irelands, will be groomsman.
