I honestly think this is direction Disney is looking to do in some form but not sure if will be this exact option. My understanding is they are struggling to get people in the hotels and we already saw early version of this in the park pass system where annual pass holders were blocked out but availability existed for annual passes staying on site. I’d predict the park pass system stays long term to limit ap attendance and will have tiers that balance how many days you can reserve or reservation window (as seen with Disney land survey) but limits will be overrode by staying on site. Having an extreme tier with 0 park passes would be this exact option; not sure Disney would go this route but would be great for me as I am
dvc and always stay on site. My only risk for them doing this is if they decided the extra park passes for staying on site on dvc was direct members benefit only.
