I made a mistake with points and learned the hard way
The concept of the travel anchor — a major experience that justifies the entire cost of a trip — is worth planning around.
Every long trip has one or two experiences that are the actual reason you went. The Serengeti migration. Machu Picchu at dawn. The temples of Bagan. The Halong Bay karst landscape. These are the experiences you'll describe to people for the next decade.
Budget planning around the anchor: identify the anchor experience first. Research its actual cost (transport to get there, entry fees, guide if needed). Build your total trip budget to include this cost without compromise — don't skimp on the experience you went 10,000 miles to have.
The rest of the budget: the days before and after the anchor are the flexible ones. More frugal accommodation, cheaper food, slower transport. Save on the journey to afford the destination.
Example execution: 3-week Peru trip. Anchor experience: Machu Picchu via the 4-day Inca Trail ($600 for the permit and mandatory agency). This is non-negotiable and the right call. All other accommodation and food are kept at the strict budget level ($12-18/night, street food). The trip total is higher than a pure budget trip but the anchor experience is fully realized.
The mistake: saving money everywhere including on the anchor, then having a compromised version of the thing you went for. Budget the rest aggressively to afford the anchor correctly.
