I have added a few sites to my favorites at work that I need to add here at home. Your thread remined me I need to sent the site addresses I have at work to my home e-mail address. At any rate, if I can get pictures or a floor plan, it will be from one of the sites I have at work, but not hear at home.
Next is your reference to "Penthouse" and category "AG". I have a Norwegian Star brochure because I will be on the Norwegian Star in October. The A1 category does have a whirlpool tub on the balcony. However, that category is known as the Garden Villa and costs $25,000 per week.
AA is refered to the Owner's Suite - I guess you can stay there if the owner is not using it.
AB, AC & AE are all referred to as Penthouses.
AD is referred to as Romance Suite.
AF and AG are referred to as Mini-Suites.
So, your refernce to "Penthouse" and "AG" has me a little confused. However, I'll get you all the info I can.
Reading the description for categories AA and AB ... luxury bath with whirlpool tub and separate shower.
Reading the description for categories AC, AD, AE, AF & AG ... luxury bath and shower. I would thus be my guess that categories AC, AD, AE, AF & AG do not have whirlpool tubs, but do have bath tubs. The other cabins all only have a shower (no tub).
The brochure has a floor plan for a mini-suite (AF & AG). If you are in an AG mini-suite, I can scan it and post it for you.
