I thought this thread is what you bring into the park - but I love the ideas for the hotel room too !
Ditto phone charger, water bottle, magic band, cell phone, money/credit card, hat, sunglasses.
We do not carry much into the parks.
We take pictures with the cell phone.
No large bags
We love the late October/November before Thanksgiving, or early December before Christmas time frame
Less humidity, little rain, cool temperatures.
The only problem may be early closure hours of the parks

But if we do the early morning hours at the parks, we do not mind a 9 PM park closure.
