The Kodak Holiday is quite an excellent little package. The simple shutter mechanism cleans up nicely and functions well just by removing the lens from the front. (2 screws).
It's a 4x6.5 negative format, so it's a *BIG* negative. And the Efke film works very well in it.
Most people think it's a joke when they see you with it, but it is truly an awesome little piece of Bakelite.
I too have a Baby Rollei, a Sawyer, and a Yashica 44. All three have good optics (yes, they do beat the little Holiday's simple meniscus lens), and all make for much more manageable package to tote around than a 6x6 TLR.
And I noticed that there is now Rollei Retro 80 film in 127 size. Haven't tried it yet, but there are 3 ricks of Efke 127 in my freezer. And I hate to admit it, but there are 30 rolls of 46mm Agfa 160 C41 long rolls in my freezer, too. (My word, that's enough 127 film to last my whole life! Yeah!)
