I agree with PP who recommends the Swan/Dolphin lounges - love bluezoo. You could also consider Rosa Mexicana and just do apps - the guacamole is fantastic.
The food at CRT is not good, IMHO, but I would definitely consider eating there. It's so iconic!
I would probably do 1900 Park Fare for brunch. I wouldn't want to fill up on a dinner there and then go to the fireworks party.
If you are looking for higher end food, you may want to reconsider Kona. We've given it so many chances over the years and it's just not good, IMHO. Maybe consider Cali Grill to end your trip if you like finer dining?
