Jill, thank you! It's looking like this is a done deal! I can't believe it, I'm so excited already! David's even hoping to come with us, but for only part of the trip (she and I will be there for about 10 days). I've done a little reading online, and I'm feeling like this will be something we can make happen, in a pleasant way. Of course, it all comes down to what Clara is like and what she wants to do that day. Thank you again for the advice and good luck on YOUR trip!
