Luggage and bags:
Take something with wheels - you might do a little walking from where you parked your car.
Clothing/Shoes/Weather Gear: I can't speak for what it's like except for July - I highly recommend bringing a light jacket for the evenings or long sleave top/sweater.
Clothing/Shoes/Weather Gear: The weather here is pretty temperate since it is on the water. Expect temperatures ranging from 70-85 degrees F during the day in the summer. Temperatures usually drop to around 50-60 degrees in the evenings during the summer. The winters are mild with temperatures ranging from 35-68 degrees.
You can wear anything you want, everyone else does!
Days will be warm but evening you will need a heavy sweater or jacket.
You probably won't need a raincoat because it seldom ever rains.
