MIAMI, March 3 -- SeaVision, Inc., a subsidiary of Allin
Communications Corporation (Nasdaq: ALLN) and Royal Caribbean Cruises, Ltd.
(NYSE: RCL) (RCCL) have announced an agreement for the installation and
operation of interactive television (ITV) systems on board two of RCCL's
luxury cruise liners. Under the terms of the contract, SeaVision(R) completed
installation of a state-of-the-art ITV system on the Majesty of the Seas in
February 1997, and will install the system on the Rhapsody of the Seas in
April 1997. The two companies anticipate additional installations on board
other ships of the RCCL fleet following the completion of the first two
projects.

The interactive television systems aboard the Majesty of the Seas and the
Rhapsody of the Seas -- known as "RCTV" -- will enable passengers to access a
wide variety of services, including shore excursion preview and purchasing,
room service and wine ordering, an activity calendar, dinner menu previews,
video "tours" of the ships and their facilities, folio review, shopping,
gaming and movies-on-demand. The system was designed by SeaVision in close
consultation with Royal Caribbean's technical, marketing and operations
personnel to ensure that it meets the cruise line's demanding service and
performance requirements.

"The decision to install interactive television systems on our ships as part
of our multi-billion dollar fleet expansion is yet another example of our
commitment to provide our guests with the best in amenities and services,"
notes Peter Whelpton, Executive Vice President of Operations for RCCL. "We
have chosen SeaVision as our provider in light of their proven track record in
interactive television and their understanding of our business and needs."

Chief Operating Officer of SeaVision. "We are pleased to work with their team
on this exciting project, and look forward to a long and mutually beneficial
relationship with RCCL in the months and years to come."
