Is it too early to plan for vacation... in December?

Since it's been all work so far this year (see previous post), I am really looking forward to a nice, long, uninterrupted, disconnected (from work that is) vacation. I don't think i can skip going back home (HK) - after all, that is where i do my main shopping, but perhaps I will venture out a bit this year and pack a 3-4 day trip to some other places. I'll see how that go.

On the other hand, my sabbatical most likely will not happen this year. For those who don't know, my company offers a 4-weeks sabbatical leave for every 5-years of service (Sometimes, i can't imagine having worked here, the same company, for 5+ years already. Many college/high-schools friends have switched jobs, even multiple times. In certain sense, I think I'm quite lucky that I found a company that matched quite well with me. Oh, back to sabbatical). They would also pay for airfare (include a companion) and up to 20-days (or 21... forgot the exact number) of lodging cost (i think it's 150/day). England is a front-runner for me at the moment, but not 100% sure yet.

I could also break the 4-wk into two 2-wk trips (taken 18-months apart). So that's another question i have to think about. Should i take it all at once, or two mini-trips instead? Um...
