I've seen two sites offer "unlimited" Seedance2 deals. Of course, you can't expect unlimited to literally mean unlimited, but I wanted to experiment with Seedance2, so I ended up biting the bullet on both deals to see how truly "unlimited" the deals are. Here are my impressions alongside every downside I noticed.

Higgsfield

I should note they don't currently offer an unlimited deal, but they had a "7-day unlimited" deal for Seedance2 recently and I assume it's something that will pop up again as they've offered similar deals multiple times before.
The offer they had was for unlimited access to Seedance2 Fast over a 7-day period. I can't remember the exact price, but I think it was a bonus for a 100 USD tier.
You are limited to videos that are 8 seconds in length and 720p resolution.
Generation time was around 10 minutes in length.
I'm not 100% sure on this one, but I think it let you have 2 prompts queued up at the same time.
The above limitations are removed if you toggle "unlimited" off, but then you have to spend credits.
I'm pretty sure there are two censorship layers in play. One implemented by Higgsfield and one that's on the side of Seedance2. I had a really hard time having it accept image-to-video prompts that included images of real-looking humans, even though the ones I tried were all AI-generated images or CG images. Edit: They recently loosened their own censorship layer so it's now easier to use images that show a real-looking human, but it's still restricted when compared to Loova.

Loova

They have multiple variants of their "unlimited" deals -- most of which are for annual subscriptions. 120 USD per month for "unlimited" Seedance2 and 60 USD per month for "unlimited" Seedance 2 Fast based on current prices.
Unlike Higgsfield, this is actually unlimited over a long period of time (one month or one year) rather than just 7 days.
You are limited to two prompts queued up at a time.
You can make videos lasting 15 seconds, but they must be 720p.
Generation times differ greatly depending on the time of day and can be very rough. If you make videos while it's in the middle of the night in China, generation times can be as quick as minutes measured in single digits. Most other times of day, though... expect generation times that are anywhere between a half hour to 5 hours. I wouldn't expect to make more than a few videos per day using their "unlimited" plan.
The above limitations are removed if you toggle "unlimited" off, but then you have to spend credits.
Loova is more permitting than Higgsfield when it comes to image-to-video. Higgsfield refused almost every single input image that shows a realistic-looking human, while Loova accepted most of my input images. It's especially likely to accept images of humans if I include it as a reference image rather than as a starting image. I'm assuming celebrities and popular copyrighted characters are always denied, though.

Runway ML

I haven't tried this one myself, so I'm going based on what other people have stated about the service.
The unlimited offer costs 95 USD per month if you subscribe on a per-monthly basis, or 76 USD per month if you subscribe for one full year.
You can make videos lasting 15 seconds, but they must be 720p.
People are speculating it's the Fast variant you're getting, rather than the full model.
Waiting time varies. Expect waiting somewhere between 5 minutes to 40 minutes for a generation. Waiting time is lessened if you generate while most of China is asleep.
It's apparently really easy to get banned from Runway if you ask for NSFW or violent content in your prompts.

I could write my general impressions on Seedance2, but it would be redundant. I think most people have learned by now it's the best video model by a long shot. The big downsides are that it's expensive to use and it can be eager to refuse many prompts.
