We are returning to Emerald this summer, in exactly the same mini-suite as we stayed in last time - so it can't be bad! We have two kids, one of 17 and one of 12. Our 17 year old is 5'9", and really enjoyed the sofa bed made up for her each night, as it is about 4' wide, at a guess. Our youngest slept in a bunk that pulls down out of the ceiling. I'm not sure I would want to be an adult on that, even though of course you could fit in easily, and - as a bonus - the second TV which is in that bit of the cabin is mounted quite high so is easy to see from that bed. The balcony isn't huge (we've stayed in some really big suites on other ships where the balcony was great) but perfectly adequate for all of us to sit out on. If you think of this as booking a larger cabin, rather than a mini-suite, you will be less disappointed - it's not terribly luxurious, but the space is good. There's plenty of room for your stuff (unlike on Celebrity where we ended up keeping clothes in our cases!) and while the bathroom isn't fabulous it was fine.
