Thanks for the preliminary answers, to crustyasp46, no I think
the terminal was a bit bigger, more upright and possibly with a more boxy looking
screen, not sure anymore because it must have been between 1980-1983 or so.
I think one was able to order things on it from the hotel, like room service but it also had
a calendar function and the game I described previously. Gosh, I feel old now not remembering.
Quite likely it had a monochromic amber screen with basic ASCII text/graphics. I am almost
certain it was a sort of all-in-one design, dare I say Apple Macintosh? But that I would have
remembered for sure...hmmmm.
I do remember "reminder" quite vividly. And the adventure game. And the room-shrinking hazard...
RRichi, I did not contact the hotel but am certain given the average age of hotel personnel that
the person who may remember would be about 85 years old by now :-& but thanks anyway
Perhaps if anything it may have looked a bit more like this>

Hmmmmmm. Anyone else?
