Mumbai flight prices were the first thing I checked, since that can change the total quite a bit. I wasn't convinced by the usual package pages at first, but this one gave me enough detail to compare nights, transfers, and hotel locations. When I looked at the itinerary, the slower pace around Phu Quoc made more sense than squeezing in mainland Vietnam. The Phu Quoc Tour Package mentioned here also helped me compare the cost against arranging each booking separately. To be fair, I expected the package to be much more expensive. It wasn't. I also checked travel insurance and a possible layover before saving the page, because those small details can mess with an otherwise simple holiday.
