Def year round!
You can theme it to the seasons or holiday.
This is what you'll see at my site next month-
My standard is my Mickey Light Pole (with color changing ears) that hubby sticks right into the ground for me. My two Mickey and Minnie Garden Statues with solar hanging Mickey lights. A Red rope light Mickey head and my Disney Flamingo.
Pretty much anything or theme that is Disney would work.
K-mart has a ton of stuff right now, I have my eye on a Mickey water fountain.
Have fun decorating your site!
