I am not trying to break any rules, just trying to figure out if this is possible. We're in the UK but my divorced parents both live in the US. We're planning a trip in 2014. The plan is to have my mom and stepdad there the first week and my dad and stepmom the second. If we were to book a 2 bedroom villa for all 2 weeks, with tickets and free DDP for us, is it possible to have them all stay with us? It would put 4 adults and 2 kids there the whole time, but two of the adults from the first week would leave and 2 more arrive. We would buy tickets for dad and stepmom when they arrive and I assume they could not take over the rest of mom and stepdad's DDP. Dad and stepmom are actually hoping to have an AP by then, if a move to FL works out in time. Is this possible? We're still not sure if we want to share a villa with relatives, but looking at our options.
