Thanks for asking this! I am still a bit confused.
I had purchased five day park tickets from
UT. Then I added two days when I booked onsite. So we want to add hoppers to our trip and want to add for all seven days if possible. On the phone they said I could add for the two days and then add for the five, but that seemed like a waste of money. Are you guys saying I might be able to get for all seven when I'm there (at the discounted amount)? Also, why would it be better to use one day first?
Did you buy the 2-day tickets because of a dining package? For whatever reason you purchased the tickets, Disney charged you their gate price for these tickets, $200.22 each. Your UT tickets were not a Disney purchase, that's why Disney couldn't access them to upgrade them at this point.
Your UT 5-day tickets were priced at a discount. Just looking at the UT website, they're selling for $309.99. Disney's price for this same ticket is $323.76.
If you added together your 2-day Disney ticket, $200.22, and your 5-day UT ticket, $309.99, you spent $510.21 for the equivalent of a 7-day base ticket. You would have to add PH separately to each of the two tickets, $63.90 x 2 = $127.80. Your ticket investment for 7 park days -- a 5-day PH plus a 2-day PH, would be $638.01. That's way too much money.
Here's how to proceed, to get your Disney ticket expense under control. First, if your Disney 2-day tickets are required because of a dining plan package, there's nothing you can do about that. It's a necessary package requirement. When you check-in, have the front desk personnel remove the 2-day tickets from the MagicBand and put the tickets on separate plastic ticket media. Put the tickets in an envelope, date and label them, and take them home with you. They'll be good to bring back to Disney on your next trip to add days to. They won't expire. Or you can give/sell them to somebody else legally. (If you keep the Disney tickets on your MagicBands, there is a possibility you could use them accidentally, and you want to avoid doing that.)
Now you only have your UT 5-day base tickets. You want to upgrade them to 7-day PHs. Disney will give your tickets Disney's current gate price credit if you use the tickets first to enter one of the theme parks. It's called price-bridging. After entering a theme park, go to any Guest Relations (inside and outside the park front gate) or any Ticket Booth at a park front gate, and add two park days, $21.30, and Park Hopping, $63.90. Total upgrade charge will be $85.20. Add $85.20 plus your UT cost, $309.99 for a total investment for you of $395.19 per ticket. Compare that price to the first figure above, $638.01. You saved yourself $242.82 per ticket, plus you have gained 2-day unused tickets with a value of $200.22 each, to use for another trip. Be sure to do the upgrade before your ticket is completely used up, at which time an upgrade won't be allowed.
Just a note about your discounted UT tickets. As said, when you actually use the ticket to enter a theme park, Disney price-bridges it to current gate price value. If you DO NOT use the ticket first when upgrading, you will only get the wholesale cost that Disney sold the ticket to UT. That's because Disney doesn't know what price UT sold the ticket to you; they only know the wholesale price. For you, that could mean you'd maybe get $275 credit (a guess) and you'd owe the difference between Disney's gate price and that amount, in addition to the upgrade cost, per ticket.
There's a few CMs who can't/won't price-bridge when it's called for. If you encounter one of these disappointing people, and you can't get the upgrade price above, politely ask for your tickets back and seek out another Disney CM who has been properly trained.
