Did a cruise in 1984 but then took 20 years off (for no logical reason we can think of!) so I'll mention our 2004 family cruise:
1). Being met at the airport by a Royal Caribbean rep and being herded unto a bus and delivered to the ship (Explorer OTS)
2). Food: so much of it. Walking around the first two days stuffing myself, being amazed at the amounts of food available, thinking this must be Heaven, then feeling so bloated by Day 3 that I thought it might be Hell! (have since learned to pace myself...)
3). The amount of activities and entertainment, all thoroughly enjoyed.
4). Missing our first port and being onboard for 3 straight days, and being glad to finally be on land again (have since learned to love sea days)
5). The Gold Medal our 15 yr old son won for playing video games
