What can I say but that Carnival Conquest was simply fantastic!
Ok I am a native Houstonian and so for those traveling from Houston it is a short drive and then to find parking, which happened to be the only item I failed to research. We found a new company that competes with others and the citys parking for a great rate of $55 for the 7 Days called Light House Parking.
Anyway, we chose Carnival Conquest after reading review after review over RC Rhapsody of the Seas and Princess Grand Princess which is also owned by Carnival, the main points were Camp Carnival for my son (2) and entertainment and activities for my wife and I (31) and mother-in-law (69) along with great reviews on food and cabin size as this was our first cruise and only had reviews to go by.
