The Ultimate Park Hopper was linked to your room in a "length of stay" situation. It expired at midnight the last day you stayed in your room, and couldn't be made to not expire. It included unlimited admission to the 4 Major Disney Parks, 2 Disney Water Parks, Disney Quest, Pleasure Island and Disney's Wide World of Sports. They are no longer offered.
The closest thing you can get to something like that without getting a Premium Annual Pass would be the 10 day MYW Park Hopper w/ 5 Magic Plus Option and opt to either have it expire in 14 days or have the no expiration option added. This would give you 10 days to park hop between the 4 major parks and 5 additional options to visit the 2 Disney water parks, Disney Quest, Pleasure Island and Disney's Wide World of Sports. The option visits do not count against your park hopper days, however if you use a park hopper day and an option on the same day, it will take one of each. Also, if you go say Typhoon Lagoon during the day and Pleasure Island at night, it would take off 2 of your options.
The tickets are available for anywhere from 1 to 10 days, however the amount of plusses you receive is based on the number of park days on your ticket, so for a 1 to 3 day ticket, you would pay an additional $45 and receive 2 plusses. On a 4-5 day ticket for that $45 you would receive 3 plusses, on a 6 day ticket for that $45 you would receive 4 plusses and for the 7 to 10 day ticket you would receive 5 plusses. To add a Park hopper option to the ticket, it is an additional $35 plus tax. To add non expiration on a 2 to 3 day ticket, it is $10, on a 4 day ticket it is $15, on a 5 day ticket it is $35, on a 6 day ticket it is $45, on a 7 day ticket, it is $55 and on an 8 to 10 day ticket it is an addition $100. None of these prices include tax, which is 6.5%.
Hope that helps clarify things.
