I'd stick with the Le Pliage. I took the large Neo Tote on holiday last year and it was great, fitted everything in and was lightweight when I used it for sightseeing.
I've just got the smaller travel tote with a cross body strap in the sale at House of Fraser which I'm intending to use for holiday/travel this year. Whilst it only has a small slip inside pocket, I've got some lightweight Kipling pouches for passport, tickets, Kindle and iPod etc. I can't fault it to be honest.
