We just priced Navigator and Voyager for a cruise for the beginning of August. Our TA quoted us: Inside $1149, Window $1299, and Balcony $1499 per person for RCL (both ships), including port charges. 3rd passenger would be $899, including port charges. These prices were with a lower price guarantee, so we'd get the benefit of price drops as we got closer to the cruise. Our TA thought that Navigator might have bigger price drops than Voyager, because more people choose to cruise on Sundays. We ended up booking Glory, based on itinerary. We're happy with our TA (she's hooked up with one of the big internet discounters, and has got us good prices on 7 cruises so far -- she's very responsive). Feel free to e-mail me if you'd like her contact info.
Last January we booked a June cruise on the Pride after pricing both Pride and Explorer of the Seas. RCL was signficantly higher in cost. By June, we saw the Explorer prices drop to the same as our Pride cruise. Yeah, we went ahead and booked a second cruise on Explorer of the Seas in August. . . the cabin selection at that point was pretty skinny, but we had a GREAT trip.
