OMG!!! I Finally caught up to the thread... Here are my impressions of weekend one:
First I'd like to say it was great meeting everyone I encountered from this thread.

I love you all but I want to send a special shout out to the coolest dude of all: Jonathan!!

I got to enjoy the Fireworks on Sunday with him and his family.
Weather: The sun is brutal when it's out so definitely bring one of those shorty totes umbrellas. I had one and I saw a number of people strolling around the park or waiting in Character lines using one.
Lockers: Consider renting one. I loved having the option to stash my purchases and back pack in them as needed. The large size is quite roomy (sorry I don't have dimensions).
Say Hi: Don't be afraid to say hi! to other Dis-ers you recognize from this thread. It puts a smile on everyone's faces when you connect at this event.
Rebel Hanger: I did it twice so I'm sure that it was nice, in fact it was awesome. The food was good and the character interactions were really fun. You can buy the glow cubes separately. I got all 3 at once.
Character interactions: Don't be afraid to talk to the characters. Compliment the Modal Nodes on their "Galactic Grammy Nomination" for their one song. Tell Darth Maul that he better behave because you have his mother on speed dial on your cell phone and you're about to call her and give her the run down on his antics. Ask if Chewbacca has applied his Frontline Flea and Tick prevention. Make stuff up like that. They LOVE it when you interact with them. Also be aware that the characters are IN CHARACTER. I was chasing Aurra Sing around trying to get her picture (She roams) She was ignoring me and stalking away. I finally got her to turn around and pose when I said "Even though I'm Rebel Scum I'd love to get your picture".
Make a list or a plan of things that you want to do: I forgot to go to the theater and see the Star Wars content. I had it on my plan but I forgot to check to make sure that I was hitting all my must do's.
Sci Fi breakfast: Definitely bring your best camera and make sure you know how to turn on your flash. Your pictures will be a blurry mess if you don't use the flash on your camera... even if you are using the movie screen to help to light the characters. Also you can order one entree and ask for parts of another entree. I had the shrimp and cheesy grits and asked for some of the bacon from the other entree on the side. Nom, nom, nom!!!
Annual Pass Posters: I picked up one each day to give away to random people. You should have seen the looks on their faces. Spread that pixie dust!
Compliment people on their outfits: If you see a t-shirt or a costume you think is cool let them know. It brings a huge smile to their faces.
That's all I can think of for now. I'd like to wish the rest of the SWW 2015 garrison the best of luck. May the force be with you!
