I have it down to 2 suitcases for our trip in September. One is the 20" Walkin Bag" that I saw on Magellan. It has 4 wheel to make it easier to glide and pull each way. You can sit on it, which I think is great because I have some issues with my knee. It would be great to be able to sit down while waiting in lines or on trains, etc. It weighs 8 pounds. The other is the bag on Rick's travel store. It weighs 7 pounds, has 2 wheels (Says it is good on rough surface), but I won't be able to sit on it if I need a chair and none is available. So which one should I purchase? Thank you!
