Thank you, vinotinto! And I did read your post linked in your signature and it was very helpful.
I do have one more question that would relate to modifications due to the COVID-19 pandemic. My daughter works for a wedding venue and as all weddings scheduled during March, April, and possibly May are being rescheduled to later in the year, she may actually not be able to take off work for our September 9-12 dates and may not be available to travel on any of the other dates included in the offer. If that happens, I'm assuming we cannot go without her since she is the lead person the reservation?
