The positive is that it'll have the larger verandah as most other 5E verandahs will have. The negative is it's location, and possibly that it's a connecting room depending on your needs or preference. I'm not as concerned about what's on Deck 5 itself as to what is below it. 5528 is directly above the Walt Disney Theatre Balcony, and I'm not sure how much soundproofing separates you from the actual theatre. Hopefully they've added quite a bit.
On the Magic/Wonder, they didn't really break out the "balcony" level, so I don't know what difference that will make. You can read the room reports from the forward Deck 5 rooms on those ships. I think some of the most common reports were noises from the theatre during nap times as they rehearsed the stage shows, and of course from the actual performance if you went to bed early. On the Magic/Wonder, the shows generally went until 9:30pm, except on nights they had adult or other entertainment in the theatre (which they did on the WBTA, but that may have been because there were so many adults on board.) On the Dream, the 3rd show goes from 9-10pm, so a little bit later.
Honestly, there are so many rooms on the ship that have positives and negatives, and your perception of which is which depends on what's important to you or what you prefer. On our August cruise, we have friends travelling with us. At the time they booked, the cheapest connecting rooms they could find were two of the square 8A rooms on Deck 5. Do they really want to be above the WDT? No, not really. Did they want to pay more for connecting verandah rooms in another location? No, not at all. So they opted for the *potential* disruption of Deck 5 (since no one had sailed there yet) instead of paying more for another location or category. [Bonus since booking - we found out that each of their rooms has 2 large portholes, so they'll have 4 large portholes across their connecting rooms! Again, positive vs negative, and the positives won them over.]
