The specific cruise I was looking at was a 4/27 sailing, Tampa to Boston on the NCL Dawn (12 nights). The cabin I priced above was a Penthouse with Large Balcony for 3 people. I would be curious to see what others get for the price.
Also, my week is again a True Platinum 1-26 51-52 float, but is deeded xmas week. I know that the deeded week for the float doesnt matter, but who knows what Starwood actually gave, and I'm not even sure II would go that in depth when assigning the value.
Edit:
I am seeing the same large discount you are seeing no matter what I use. I am seeing about $1,770 to $2,100 off depending on the week I use. It is the cruise or line and not the week you are using. I will post the specific discounts as soon as I run them.
These are the discounts over NCL. Deduct $300 for the ship board credit. I am assuming you do not get that with II but I could be wrong.
Generic trader $530 maintenance fee - $1,783.46
Ocean Pointe Pres. Wk - Studio - $1,715.56
Ocean Pointe Pres. Wk - 1BR - $1,933.96
Ocean Pointe Pres. Wk - 2BR - $2,001.46
Ocean Pointe Pres. Wk - 3BR - $2,068.96
Ocean Pointe lowest TDI possible 90 days out - 3BR - $2,017.06
It is a very good discount, but the much better value is in a non-prime week, if available. There is very little difference between the best and the worst weeks given up. Only $50 difference between dead season and the best week at Ocean Pointe? It doesn't make any logical sense, but that is II for you.
It is a very valid consideration. I had no idea that you could get that big of a discount on any cruise.
You are right, the discount increases with a more expensive room type. The Generic trader $530 maintenance fee turns into a measly $648.42 off NCL with the cheapest room type.
