Every airport and similar ports of entry will have a local sim shop usually. In my experience it would take something like 20 min per country to set up, and depending on your phone you could have the local and the US sim active at the same time (and choose what consumption goes to which sim).
imo not worth to overpay for a home contract, especially since it is very possible you get low priority in data roaming and your speeds might be low (eg. vodafone roaming sucks)
