My girlfriend and I just came back from our 8 day cruise on the Miracle from NY to San Juan, PR; St Thomas, USVI; & Grand Turk, Turks & Caicos.
Embarkation and debarkation were really easy. No issues at all. No problems sneaking booze on either.
Our room was an aft view extended balcony (Room 7300). The view was great and we will definitely look for this type of room again. The balcony could have been a bit bigger, but the view off the back of the boat was worth it.
