@Naomeri said above, you don’t get any of that with the silver membership. Current gold members get an opportunity to purchase platinum access, then current silver members can upgrade to gold. The spots for new people are almost always just silver.
Additionally, if you were to get membership, I believe the the perks don’t start until Jan 1, 2027. So you wouldn’t be able to register using your club rundisney membership until after then, which means you would likely only have it for wine & dine in 2027.
It’s very convoluted so just be sure you know what you’re getting in to.
