I just spoke to Tortimer this morning at the wishing well and he told me he was going on vacation from January 16 -22.  He asked me to watch over the Lighthouse while he is away.  Since this is my first time playing AC, he asked me to flip on the switch and get the town to help me turn on the lighthouse between 6pm to 10pm.  Where can I find the switch???? how do I go about doing this?? Please help Thank you so much!

Very Simple, on those days he is gone, go to the lighthouse in between 6 and 10pm. The door in the back is open, so just walk into the lighthouse. You won't be able to see the door though. Once inside, pull the switch on the right side of the door by pressing the a button. Keep doing that until he comes back, and your prize is a box of chocolates

Yes - It's very neat because this is the only time you can actually enter the Lighthouse. I always thought that was really cool.

Yeah he just went on Vacation in my town to and i got The Same Job!!!

Your prize may be chocolates or a lighthouse model. Both times I've done it, I got the lighthouse model.

I have always gotten the chocolates.

Wow awesome. He went on vacation for me too, & I believe he does this for every AC:GC town around this time.
