I usually say... "It depends"
Sometimes I say "how much money do you want to spend?"
Sometimes I say "best for what?" or "favorite for what?"
Sometimes I say "well, I like this specific kind of cruising, but you have to realize I have my personal reasons for what I like."
I often mention, "Well, I live in Phoenix, so I am not a typical "tropical" cruiser."
Sometimes I ask people "where do you live?"
Sometimes I ask them, "where do you want to go?"
Sometimes I ask "are you more of a luxury hotel, or a campground and sleeping bag kind of person?"
Sometimes I ask, "what's more important to you, a good meal or a good show?"
Sometimes I ask, "what would you rather do, dance to loud music, or read a book in solitude?"
