guess i just get confused with 4 nites, i'm thinking that your credits must have to be used by end of the 4th nite, but in my case being i don't arrive till late afternoon the 1st nite,am glad to know i'll have the credit to use till the end of my 5th day, ( even if I check into another resort ) i can still use those credits till the end of that 5th day , yes?
