My problems are all solved! I will have a room with a view at the Westin Ka'anapali South for the Sat/Sun nights, which will give us hang-out space for everyone and even a bedroom for the kids (or adults) to take a nap. The air conditioning will make it so much more comfortable than taking a chance on the weather that day too.
I am overwhelmed with gratitude as a TUGer (who wishes to remain anon.) has kindly gifted these nights as a wonderful ending to this important family trip. Thank you, thank you, thank you! This is just the best possible way to end this vacation, and I know everyone in my family will appreciate it so much. TUGers are just the best.
