I live in the UK, and primarily use Marriott hotels in the UK.
I have a load of points, and know I can use them for hotel stays, as I have in the past. But I cannot find out about upgrades using points in the UK. For the US the information is freely available, but not for the UK. What I would like to do is book 5 nights in a UK London hotel on points, (so 4 nights points = 5 nights stay) then pay for an upgrade to a room with executive lounge access. I don't mind if I pay with points or money.
Can anyone help me to find out if this is possible please?
