Disneyland Hotel in Paris Two Nights Help Please First Time

[BeachMouse1]

So we are stopping at Disneyland Paris and staying in the Disneyland Hotel which I understand is onsite. We will be there mid September
We are there two nights and getting the premier access ultimate.
So will we need to plan on all day open to close in the park to get things done?
We are Disney World people and have no idea what to expect here?
Where would we eat? We usually like a sit down meal per day
Will we be able to do most rides and attractions or should we prioritize? If so which?
Any special activities we should do?
Basically we are looking for any suggestions, tips, tricks, recommendations

Thanks
