As the title suggests basically.

I'm 20k short of platinum and my next trip isn't until October 4th!

I do 2-3 trips a year as in UK. Can't exactly pop over to Vegas to stop them expiring.

Or are there any ways I can earn 20k without visiting Vegas?

I really want platinum as will be booking a Royal Caribbean Cruise in the New Year and the extra perks look good.

I do have a host I could email, but it seems a little trivual to bother him with
