This was out 15th cruise but the first time flying to a port which was our only "worry".
The process was painless and compared very favorably to our typical drive to the ports.
Jewel was in good shape, a little dated in some areas but a solid ship still with a good crew.
Cabin was a standard size/shape with a Pullman bed above the regular beds.
Everything seemed to work fine, the sink was draining slow but no big deal.
Balcony was HUGE, standard width but probably about 10 feet deep with 2 loungers and an extra table to go with the normal 2 chairs and a table.
Noise coming up from the Centrum was a little noticeable but not bad enough to keep us awake at night.
Did not take the time to any excursions/activities in San Juan but the embarkation process was very easy. Landed at the airport about 11, grabbed a cab and we were on board and eating lunch at about 12.30 after breezing through the terminal.
