DH and I took our first cruise on HAL . . . and we were blown away and hooked on cruising! We then did a RCL and 2 Carnival cruises. We didn't think that the service or the food was that great on RCL but did like the open airy atrium and other common areas. Carnival was fun but again, the service and food were not what we experienced on HAL. We've booked our first Celebrity cruise in December (Zenith out of Miami for 5 days.) If it is equal to or exceeds HAL then I'm ecstatic!
