Every idea stated is good stuff :yes: .
I think the most important aspect is often the most overlooked; it's about the mystique and intrigue of it. Keep her on her toes and wondering, always allow her mind to ponder the possiblity of the event.
Here's one which I used on Mrs. K not too long ago:
I called her cell and left a message to shower and freshen herself for an extraordinary evening. That's it. Be promptly ready at 1800 and I'll be home to swing by and get her.
This alone made her giddy and amped up her anticipation.
Next, we head east on I-4 Orlando bound (which is all I would leak). We got to Benihana for fantastic sushi and conversation and lovey dovey kinda junk (I know, I'm a hopeless romantic. Sue me! ). From there we walked Citywalk and I took her shopping and some cigar pontificating. Once we left there we headed back towards the house but at the last minute I pulled into Toys R Us and we chased each other around the store shooting each other with nerf guns!
I don't have to elaborate on dessert once we got back home
:crazy: !
It truly is all about the spontaneity of the thing. It's not hard. If you find something fun and enjoyable she'll become attune to your enthusiasm and get crazy with it.
