We were on Infinity her maiden year in Hawaii (April '01).....lots of bugs needed to be worked out. We were not impressed.
HOWEVER: We booked 14-day Trans-Canal on Infinity in December 2002 and it was like a totally different ship: in short WONDERFUL CRUISE ON A G R E A T ship! :-)
(Guess they got the bugs out!)
We were on Infinity for a 3rd time Dec. 2003 for another 14-night Trans-Canal - and again the ship was in wonderful condition and the staff great. (as was the itinerary)! :-)
We've cruised on Summit 2X and Infinity 3X with Millie coming up next May - so far we love Summit and Infinity equally!
Have a wonderful Trans-Canal!
