In 2004, all tickets were park hoppers. Only price difference was if you bought at WDW, or not-WDW. (I think AAA was an option for lower prices, so was Disney store- including MCO, mail order, and maybe some offsite hotels). Child price = ages 3-9:
adult 1 day =$54.75
child 1 day = $43.75
Adult 4 day = $202 (not-WDW) and $219 (gate price) = $50.50/54.75 per day
child 4 day = $162 (not-WDW) and $176 (gate) =$40.50/44 per day
Adult 5 day = $230 (not-WDW) and $249 (gate price) = $46/49.80 per day
child 5 day = $184 (not-WDW) and $200 (gate) = $36.80/40 per day
Adult 7 day = any ticket over 5 days was a park hopper plus (plus = water parks, mini golf, Disneyquest)
Adult 7 day = $316 (not-WDW) and $342 (gate price) = $45.14/48.85 per day
child 7 day = $253 (not-WDW) and $274 (gate) = $36.14/39.14 per day
Days 6 and 7 still cost $43 each.
AFTER MAGIC YOUR WAY:
adult 1 day =$59.75 (non hop)
child 1 day = $48
Adult 4 day non-hop= $185 = $46.25 per day
child 4 day non hop = $148 = $37 per day
Adult 5 day park hop = $217 (not-WDW) , or $193 non hop/expiring =$43.40/38.60 per day
child 5 day = $184 (not-WDW), or $155 non-hop/expiring = $36.80/31
Adult 7 day park hop= $223 (not-WDW) and $199 non-hop/expiring = $31.85/28.42 per day
child 7 day = $186 (not-WDW) and $160 non-hop/expiring
Adult 10 day park hop/expiring = $232 =$23.20 per day
Child 10 day park hop/expiring = 193 =$19.30 per day
Adult 10 day NON-hop, NO expire = $308 = $30.80 per day
Child 10 day NON-hop, NO expire = $267 = $26.70 per day
Adult 10 day hop, NO expire = $332 = $33.20 per day
Child 10 day hop, NO expire = $293 = $29.30 per day
Notice the difference between 5 days and 10 days is just $15 total, or $3/day! ($232-$217)
You could also split a 10 day no expire ticket into 2 five days trips and that equaled $166 per 5-days ticket.
In this era, if we went for less than 10 days, we often bought the extra days/no expire option, and used the leftover days for short trips, because then we'd get 1 day for just $31. I pretty much just always kept some leftover tickets on hand.
In this era, we also got in the habit of going to the parks for just a few hours on arrival days. Where we would have previously spent arrival night at the pool or Downtown Disney, we'd go into a park for a few hours instead. So technically, we didn't add a full day, more like 4-5 hours.
