Honestly, a full week on Lana'i is too long - unless you're a veteran Hawai'i visitor who is looking to specifically get away from everything and everyone and set aside any desires to see new or old favorite things on another Island.
Also - lodging is very expensive on Lana'i - you have three hotel choices, and two are Four Seasons managed resorts. The third is a nice hotel in town - but you'll need to take a bus to the Manele Bay resort if you want beach/pool time.
3 full days is about right for Lana'i - and it's easily combinable with time on Maui when you use the convenient ferry service from Lahaina.
