@jakedduck1 Great idea, we thought of that when we went to Hawaii in 2017, but we have spent a lot of time in LA and SF so didn't feel a need to go there, and I don't think there were flights direct from LV to Hawaii. That time we ended up just doing one extra day in Hawaii, an R&R day after out long day of traveling. If we were to go now we would probably spend a night or two in Denver with my son.
I wish Grand Canyon was not so far from the big airports, my husband has always wanted to go there. It's about four hours from LV and four hours from whichever airport in AZ so that was not a good option.
The other couple just seems very opposed to such a distance but now I realize why -- they want to go for five days. Hawaii is a long way to go for only five days. They travel a lot so this is just a brief, sunny break for them.
