not sure about the carpet question.
but if i remember correctly you can stay how long you want to in the trophy room. I went in March where it is much more quieter than the summer months.
That is the long hall where all his Gold & Platnium records are on either side? Have i got that right? Sorry i am still half asleep.
To be honest the trophy room was too much, there are framed records in there from the floor to the ceiling. Sends ya mind in a spin.
I am sure that someday you will get ya dream and go and chill with Elvis in Memphis.
I had to wait 12 years
