Getting frustrated with the cribs hotels provide (they're always play pens, not cribs!) Can anyone recommend a good, inexpensive, lightweight travel bedside crib?

My friend, a frequent traveller, uses and swears by the Brica Fold N Go Travel Bassinet. It is light, folds down to be really flat and despite all that, is super sturdy. She bought it on Amazon.com Below is a picture of how the Bassinet works.
