We have several different Travel Pros.  More often I like the 22" carry on for convenience.

On cruises this larger one is nice because you can wear lots of different cloths for formal and ports of call and size is less a problem because it gets loaded and unloaded at or near your car.  The wheels make it easy.

We take two.  One for each of us.  My wife takes more cloths but I have large feet, big shoes, and wear large clothing sizes so I use the larger space with some left for bringing home treasure.  Truth be told CostCo and Sams also offer this size for about half the price.  Lower quality but still well made.

If you travel often enough you can test yourself by asking, when you get home, if you wore everything you took with you.  Often I had to answer that I could take much less since many things were not worn.  Cruises might be different since you can change for dining day after day.

There are lots of good suit cases out there.  For the money this is a good one.  We tie ribbon on for I.D. from a distance.
