It's great to see you here today at planDisney, Christina! I'm so glad to be able to answer your question today.
I did some double-checking of your potential dates and I saw what you saw, which is no availability at any of the All-Star Resorts during the week that you wanted to visit. To confirm this, I recommend
calling the hotline for Disney Resort Hotel Reservations. They'll be able to confirm for you what the availability is for the end of February and let you know what other options you have for
Resort Hotels.
Are your dates flexible at all? I suspect that February 21 through February 23 is sold out because it's the weekend of the
Disney Princess Half Marathon, so if you're able to push your vacation a little bit earlier or a little bit later to avoid that weekend, you may be able to find availability at the All-Star Resorts.
I hope this answers your question, Christina, and please let us know if there's anything else we can do to help you plan your magical vacation!
