Papa...from the sounds of it your wife shouldn't need to many bags ...after all...how many bottles of lotion will she need?

Just kidding.
Back to the topic. I'm a "what if" packer...which also means pertty much everything but the kitchen sink. We have tended to WAY overpack. But I'm not one to use my vaction time on the ship in the laundry room...I'd rather tote extra stuff onboard. Now thing about
DCL that I like is they don't really have a "limit" on how much you can bring. It's just a matter of how much space you have left in your statroom.
Both cruises we have managed to MAX out our luggage limits (what the airline will allow) so we've EACH had 2 suitcases, 1 carry-on and 1 personal item...plus sometimes a purse

. That adds up to 8 suitcases (rangeing from XXL to a Large med) 4 carry-ons (small rolling suitcases) and 4+ personal items like a laptop. It's alot of CRAP and at times can be hard to manage. Mostly when were transfering from one area to another where we have to lug everything with us...not to mention the more stuff you bring the more work you have to do on Friday night.
To break it down we have
1 bag for the snorkel gear
2 garment bags with our formal wear and semi formal wear
1 bag with misc items like pillow cases, glow sticks and 'suprise' goodies for the girls.
4 bag for each of our clothes and shoes.
One carry on with camera gear,
the laptop as a carry-on
A tote bag carry on with misc items (books, travle docs etc)
A carry on bag for each of the girls with stuff to keep them busy on the 6 hour flight (DVD player, Gameboys, movies, CD player/Mp3 player, color books etc...)
Anyhow...I SWEAR this time we will cut back and take less.

We've found that on both cruises we tend to wear our favorites more than anything else... Our girls will wear their swimsuits just about everyday...so I figure 2-3 swimsuits and some cover-ups will pertty much be all they need for daily wear. I'm sure I can come up with evening wear to mix/match to cut back on how much we bring.
Anyhow..I'd love to learn the trick of packing ONE bag each

Now that would be CRAZY-COOL!!!
