Riding a mountain train through the Swiss Alps in May or September means clear views, cool weather, and quiet towns. You get panoramic rail routes and fresh Swiss chocolate without peak summer crowds or high winter prices.
A typical two-week trip costs around $3,500 for flights, train passes, and lodging. You don't have to drop that whole amount at once or pay interest charges to make it happen if you use a simple plan.
Remember, an intro period is a strict deadline, not free money. If you still have a balance when the 18 months end, regular interest rates kick in on whatever is left, so stick to your payment plan.
