I also love carrying one card with me, I take my $500 GC's with me to Disney and I love to flip that card out to pay for all our food and necessities, nothing like eating and drinking for FREE! We have DVC so food is really the only expense we have. It's easier for me to keep track of the balance with using only one card too, I put a little sticker on back and at the end of the day I write the balance down for the next day. I usually bring two $500 with me every trip if we go once per year....this year we are going twice and I'm pretty sure I will be able to cash out for my second card before we go but our second trip we'll have to eat cheap because I'll only be bringing one on that trip!
