I won a spa club balcony upgrade from a balcony room last December for $150-$300 total. With 3 adults cruising and getting the spa and larger bathroom we got a screaming deal! This was back when capacity was at 30% so I’m sure that had to do with the lower price. Be aware that on the Bliss (not sure what ship you are on) These rooms are under the pool deck and were noisy in the mornings when they start moving the loungers out. If you like your room location now you might want to stick with it and buy the passes.
