I cruised with my family over spring break on the Epic and we all absolutely loved it! We booked 2 mini-suites with 3 in one cabin and 2 in the next door cabin. The cabins were plenty big enough ... tons of storage space. The 'bathroom' was a joke with the frosted glass doors giving no privacy. We quickly got used to it.
The ship was fabulous - water slides, rocking climbing wall, gym, lots of outdoor space, etc.
I paid $140 for use of the spa facilities. Unfortunately, the spa was overbooked and every time I went there, I could not find a spot. Did not get to use the saunas, stone benches, private balcony, nothing ... very disappointing.
9086 & 9088: Great balcony, very convenient location - near elevators and stairs. Surprisingly very quiet for the location.
