Sorry, on my way out to a grad party - only have a sec to address the first comment on my post.
Son-in-law is military - married to my daughter.
In Jan the whole family (-) SIL went to WDW. DD used her military ID to get SIL's 5-day freebie and (5) companions @ SOG (no tax there either).
We upgraded the 5 companion tickets to include the WP and Hopper options, so total was $149 each for initial purchase @ SOG.
**Note: we were told military person's freebie cannot be upgraded at all.
Anyway, got his and held onto it for him because he will go in Dec w/ us.
Took the 5 $149 companion tickets from SOG and went to the window @ TTC, and upgraded those to regular AP's.
Total cost for each AP between the SOG counter and the TTC window, was ~$306 (not sure exactly, but within a few $$ of that).
Now, if you want the WP option to be valid, you must get a Premium AP upgrade which will be more.
The way to figure your costs is to see what a /5-day-hopper-WP/ ticket is @ WDW.
Then see what an AP costs @ WDW -whichever you plan to get, reg or premium.
The difference between the two, plus any applicable tax, is what you will still have to pay above the initial $149/ea for the upgrade to the AP.
I hope that makes sense!!
It seems about as clear as mud!!
I just don't have time right now to check the costs on Disney's site for you.
I'll check back later this evening to see if you still need help.
Sorry!!!
