Four hours is fine ... an overnight stay would be excessive!! Ignore the Cabana, just beam that newly-wed smile all over the room!
Be honest, you're just waiting for a bludgy aircraft. What a nice place to wait ... while discussing what Auntie Mildred was wearing, how Cousin Charlie can drink do much whilst remaining vertical, and what you're going to do to each other when you get to LAS
A long leisurely approach is often the best ... and very best wishes to you both.
