• Attractions/Activities: 10-15% ($510-765)
• Transportation: 5-10% ($255-510)
• Contingency: 5% ($255)

Per-Day Meal Budget

• For 2 people, 3 meals/day
• Budget: $75-100 per day for meals
• Average per meal: $12-17 per person

Accommodation Budget

• Per night pet-friendly hotel: $200-300
• 6 nights total: $1,200-1,800
• Or split between budget/mid-range options
