The Seattle N Gates lounge is brand new and ginormous and amazing, if you have three hours, skip the other lounges and go straight to N gates, C lounge is small, D lounge is two floors but also small, It is the original lounge
i’ve been to all three lounges, I would take the quick underground tram ride To N gates, And go to the lounge there, at the end after you’ve eaten , If you still have a tiny bit of time left and are curious, you can go check out the other lounges, but the food is the exact same in all three, but the end gates one is a lot bigger, like a lot a lot bigger, many thousands of square feet, and has very nice new furnishing
oh, and you asked about views, N Gates lounge has the best view, D gates lounge, You just get to see all the planes parked, no view of the runway or beauty of the Seattle airport, C gates lounge, Has a small view, but nothing compared to N gates
