The honeymoon budget mistakes that show up after you've already booked

The headline cost of a honeymoon, flights plus hotel, is usually the easy part to budget for. It's everything around that number that tends to blow past what couples planned to spend.

The costs that get missed

• Resort fees and destination taxes, often not shown until the final booking screen
• Airport transfers, especially at remote or island destinations
• Travel insurance, easy to skip when booking excitedly and expensive to need without it
• Tipping norms in the destination country, which can add a meaningful daily cost in some regions
• SIM cards or roaming charges for two weeks abroad

Build in a buffer, not just a total

Add 15 to 20 percent on top of your planned spend as a genuine buffer, not an aspirational "we probably won't need it" line. A honeymoon is exactly the trip where you don't want to be doing spreadsheet math three days in because an unexpected cost has thrown off the whole budget.

Currency matters more than people expect

Card exchange rates and foreign transaction fees can quietly cost more than a poorly-timed currency exchange booth. Check your card's foreign transaction fee before you leave, and consider a travel-specific card if you don't already have one.
