They're not Disney owned properties (I think they may be Starwood operated?) so they do not have much Disney theming. They also have resort fees that are charged per night, so make sure that is factored into your total.
They do not have Magical Express but that's a moot point depending on when you travel. I believe the MK bus from Swan/Dolphin is also dropping people off at TTC now, though I'm not sure if that's a pandemic temporary change or something new going forward. They don't use Magic Bands to open room doors, and I believe you can't charge back to your room with MBs either.
In "normal" times, they also do not offer dining plans.
