DH and I are doing a little 2 week roadtrip to USA for my big Birthday soon. DH thinks we just use our usual visa card - but looking at it, seems like charges will mount up as we will be staying in different locations/ eating out etc. Does anyone have any advice for the best travel card to use so that we don't get hit with charges too badly? It's the first time we've done this type of holiday, moving around a lot, so any help would be appreciated. TIA
