There are a couple of conditions to keep in mind. The first of which is that the included Hulu subscription gives you access to the platform's ad-supported tier, not its more expensive ad-free plan. Moreover, the base 200Mbps plan, which costs $40 per month, isn't included in the deal. However, it still comes with a free year of Disney+.
One other thing to note is that you'll need to cancel the included Disney+ and Hulu subscriptions if you don't want to pay for them beyond the time that you have access to them for free. Otherwise, they'll automatically renew, costing you $13 per month together. The promotion ends on September 23rd, after which it's possible to redeem the trials until December 23rd. Lastly, the deal is also available to returning customers.
