This was my 2nd sailing onboard a Voyager-class ship and 4th cruise with Royal Caribbean. The Explorer is a beautiful ship and extremely clean. They do a wonderful job of upkeeping these ships.
We had a Promenade cabin on deck 8. The promenade staterooms are a very nice change from the normal inside stateroom. The cabin had adequate space and storage for the two of us. I would book this category again if price were an issue.
Service was great onboard the Explorer. Our dinning table was situated right next to the Captain's table. To our surprise we were invited to have dinner with the Captain one evening. (Quite the experience!)
