Hi New_Cruiser,
I am just trying to help...Can you upload a screenshot of what you see on the Royal Upgrade offer? Please black out any information that is sensitive or necessary to keep private.
I searched, Nothing on the website says Bridge tours are included with GS cabins, I suspect the booking agent made the suggestion this is first offered to SUITE guests as the tour often sells out?
With your skill in the casino $450 should be no problem...I have only ever been offered a t-shirt. Attached is screenshot of GS from Independence of the Seas.
Enjoy your trip - This might help answer your questions.
The Information is available - I did a quick search, this is what I found.
For an Alaska cruise I would go for a cabin with amazing views.
The ships are smaller which allows them to move into tighter spaces, I have been on sister ships to Radiance of the Seas - I prefer larger ships but NOT for this cruise itinerary...smaller ship is better.
