Radisson goldpoints plus - Bed Descriptions

Sorry if this thread is somewhere already .........but figured if I stick it out there it will get answered quickly. I am an SPG member and started using Goldpoints based on some of the locations......Question......On the website how on earth do I find on how to choose the bed I want ? It comes up with prices & sleepnumber bed etc., but nowhere do I see where I can request a King or something ? Am I just new to the site and can't figure it out.

Ususally when you continue the booking there is a drop-down menu on the right side. There you can choose the bed type.
This is the case with most bookings.
Sometimes, for reasons unknown, you can`t choose it.

IMPORTANT: Very often you will find a statement in the ratedescription "bedtype will be confirmed upon arrival". If this is the case I suggest requesting a bed type in the comments box.
