I am with you, TinaBear81, as yes even though obviously the free breakfast is rolled into the room price, I cannot possibly emphasize enough what a great time and mental energy-saver it is stuffing yourself silly at your hotel before heading out for the day. The only year so far we stayed at a place where you had to pay for breakfast it resulted in our group going to Patachou instead, which, while amazing, also took like 2 hours instead of 30 minutes, which is a very real difference when you are trying to maximize four days, obviously.
Oh, but yeah, and the more years I go to Gen-Con the more snacks and drinks I bring with me. Or sometimes order, but I have been having a lot of fun exploring the fancy organic aisles at grocery stores for snacks and drinks I have never heard of in hopes of finding new favorites. Sometimes it even works! Regardless, it helps me skip lunch, and the associated endless waiting in the heat at food trucks, to just carry something with me to power through to a normal dinner.
Good call about the laundry on Sunday night, too. Definitely something to consider now that I am finally able to stay until Monday for the first time, uh, ever, in my years of going since 1997.
