Like everything, price varies. Currently $31/per person/per day for my April cruise. Currently undiscounted Premium WiFi is $24/per day and Premium WiFi 2 devices is $43/per day.
For SHORT (3 nights max) cruises solo it was worth it for me at times when the price dropped for the similar Royal Caribbean offering as I was going to purchase WiFi anyway and I enjoyed the welcome lunch (which I'd take out and eat up at Johnny Rocket's outside tables). Royal Caribbean delivered your carryons during the lunch to your stateroom (they didn't let you drop off early before staterooms cleared as Celebrity does).
It's a daily price for the length of the cruise and everyone over age 6 listed in the room has to purchase.
