We are staying on-site so we will have the 30 minutes extra. I am going to have to research what is open during that early 30 minutes.
You can see what is open during Early Entry with a recent update from @wdwmagic -
Remy's Ratatouille Adventure added to Early Theme Park Entry for Disney World Resort Hotel guests
Resort hotel guests can join the standby line 30 minutes before regular park guests.
