Thanks! I just cut and pasted that from RCCL's website. I just could not figure out how $39 per day for three people for a 4 or 5 day cruise could equal $117. Plus I just cannot focus today.
It makes a lot more sense now that someone with a clear mind explains it.
I guess when we cruised RCCL previously I must have just mentally rounded off $9.75 to $10.
