In 80-90s with Formal, Semi, etc, packing 2 Suits, Sport Coat, 4 Slacks, 6 Dress shirts and couple Dress Shoes I already was at 2 Suitcases or included a very Full Garment Bag... Been hooked on Cruises since day one and hate pay for extra Airfare to complete multiple Cruises. By time had 10 Cruises of 7 nites in 2001 started 9 & 10 niters, 4 cruises after those 12-13niters, 15th & 16th Cruises were 13 & 10 niter B2B & 2 yrs after/since only do B3B-B4B of 30+ nites. Until this yr had only completed a single Cruise of less the 10nites in last 20yrs. So yes I still take 2 Suitcases, not too much formal but not going ever wash in my sink, run out Clean Clothes or ever put dirty clothes back on after a shower. Wash & Fold helps.
