There are a lot of posts comparing the Senator lounge to the Welcome lounge, but what if you don't have Gold status?
I'm only Silver with US and flying business class PHX- DFW, DFW-FRA, then FRA-BCN with a 4 hour layover. Is the Welcome lounge worth the hike if the business lounge is your only other option? I'm thinking a shower is going to be very nice after leaving PHX at 7am.
Also not sure how long the walk is or what security is like at FRA if we go to the Welcome lounge and then try to find our flight to BCN.
