In general I don't find the Universal package deals all that much of a deal - the rules for cancellation are also a lot more strict - I think its 30 days instead of 5 days..
I have had times when it saved my like $200 over booking a discounted rate and getting tickets - but in general I find it better to buy an AP and then book a room with the AP rate. Depending on the AP you also get food discounts.
BTW - Universal does sell a 14 day ticket with packages in the US - its the "All Parks Unlimited Ticket" for 2026 - so you can go to the parks for 14 consecutive days - including
Epic and the water parks. I got this in the past and then upgraded it to an AP. Was a bit of hassle but did save me some money.
The one issue at this point that makes that difficult is the lack on clarity on APs and Epic for 2026 - and of course what will the AP cost.
Also - I don't see it yet for 2026 - but I see it for 2025 - you can book packages that include an AP - so you get the discounted AP rate and an AP ticket. I'm not sure its worth it - but something to be aware of I guess.
