In 2026, a one-week trip to Hawaii requires a significant budget, though costs vary by island. For a mid-range traveler, you should budget approximately $4,000 to $5,000 for a solo trip or $7,000 to $9,000 for a couple. This includes round-trip airfare (averaging $600–$1,000), mid-range hotel or condo accommodation ($300–$500 per night), and car rental ($70–$120 per day). Food is a major expense; a "comfortable" daily food budget is around $100 per person, covering a mix of food trucks, casual cafes, and one nice dinner. Activities also add up quickly, with popular tours like a luau, snorkeling excursion, or helicopter ride costing between $150 and $450 per person. If you are a budget traveler, you can potentially manage on $2,500 per week by staying in hostels or Airbnbs outside major tourist zones, eating primarily from grocery stores and plate-lunch trucks, and focusing on free activities like hiking and public beaches. Conversely, luxury travelers should expect to spend $15,000+ for a week at high-end resorts like the Four Seasons, where rooms often start at $1,200 per night.
