Rice fell to his death over the balcony of his deck 9 cabin four storeys to deck 5. Police were not able to board and begin an investigation until Saturday, a day later when the ship finally completed its voyage to the Port of Miami.
Brian Rice is survived by his wife Diane and three-year-old twins Brian Jr. and Bradley, and his parents and three siblings who were not on the cruise.
"Anyone who knew Brian knows how easy it was to call him a friend," reads the Go Fund Me campaign which was started to help his family "while they go through the grieving process."
The campaign has already raised over $11,000 of its $15,000 goal with some of those donating claiming to have been on the boat at the time of the accident.

"I happened to be on the 5th floor at a restaurant when the tragic incident occurred," wrote one donor.
"We did what we could do to until staff arrived. I tried to console his wife and keep her inside, so she could not see her husband in such a state. My heart is so heavy right now."
Vance Gulliksen a spokesperson for the cruise line said that they were providing support to the Rice family and that "our thoughts and prayers are with the guest's family."
The 3953 passenger, 15-deck tall ship Carnival Horizon is just a year old. Having been launched in 2018 it is the largest vessel in Carnival's fleet.
This accident follows after a development in the case of Chloe Wiegand in which the eighteen-month-old girl fell to her death from a Royal Caribbean cruise in July. The child's grandfather Salvatore Anello was charged with "negligent homicide" on Wednesday, after a Puerto Rico court deemed he dropped her out of the ship's window.
