When we went to the bay area for Zach and Christy's wedding we stayed, along with the rest of my family, in a hotel with suites and, um, a higher standard of service than the hotels we usually stay in (i.e. on the
Great Cheap Road Trip of '10). The kids were amazed that not only did we have two rooms!!! but that every day when we came back the rooms had been restored to their original splendor of cleanliness by magical house elves. We explained about housekeeping and all agreed that it was very nice of those people to come in and clean our rooms and make the beds for us.
When we left, the kids wanted to leave notes thanking the housekeeping staff and I thought that was a nice idea. I wasn't paying attention when Daphne asked me for our address and phone number but apparently she wanted to make sure the housekeeping staff of the Embassy Suites could get in touch with us later, if need be. It's a good thing she doesn't know what a social security number is because I'm pretty sure she would have insisted on including that too. I took a picture of the notes because they were so dang cute.
I'm still not sure what it is we're "hopeful" about, but I'm assuming it's that magical house elves would show up at our apartment the next time we're out and clean up our mess. So far, no such luck.
