I might be a wee bit obsessive. Meaning I run a cost anaylsis on cruises. Normally I run 6 different cruises through my spreadsheet and do cost comparision. The eight day is cheaper per night cost. This include pet sitting etc. So from a cost stand point eight days maybe slightly more expensive but it's a better value.
14 day was my longest and favorite. After seven days you realize you have another seven it's awesome. People have said don't you get sick of being on the ship. No why the heck would I get sick of someone cleaning my room, making all my meals and having wonderful nightly entertainment.
People confuse me.
The 4 days are my least favorite. I just learn the ship and they toss me off. How is that fair?
