We are booked in an SV middle on APEX..deck 10.. Although we have enjoyed an SV on EDGE with the the 4 mdrs it was not our first choice.
AQ Class with BLU and the thermal suite was priced too high, so we had to go lower..We like the IV..nice and quiet & adds space to the cabin..no wjbd or rain out there.
The SV EDGE cabin was located at the end of a nice hallway and was large (long and narrow) with a huge balc. The balc did not get much use.. there was little shade, and very noisy next door neighbors.. ran a 24/7 frat boy type party outside on their balc!
We did enjoy a nice sky and sunset view. Not much soot and really no vibrations. We did hear music from EDEN , so happy we will be up on 10 next time .
