I am currently looking for a set of card tiles/tile cards to take along on our summer vacation
Since you considered the Jumbo edition, weight and size don't seem to be an issue. Therefore I highly recommend getting the Club Edition with the thick tiles in the handy bag:
There are no tile holders, as the tiles stand for themselves and it is good for transportation with that bag as long as weight isn't critical otherwise a card version might be preferrable. The tile quality is fantastic. They are "clacktastic" and if you like you can play 3 or 4-player Lexio with them as well. Almost as good as the real thing.
