We had to cancel an April trip to Disneyland when DH wound up in the hospital with chest pains 2 days before we were to leave. As hearbreaking as it was, we are now rescheduled for next week... our first trip!
Take care of yourself, and go when you feel up to it. I can't imagine having had something happen while we were on vacation, so we feel pretty lucky the way it all turned out. Good luck to you!
