Is this correct? (Expense question for Japan trip)?

Question:

Avg. flight price per person: $1200 -1500 USD (US to Japan)
-Hotel: anywhere from US$50 to over $650 per night. (We're staying 4 days.)
1500X [12(members) + 4 (Chaperones)] = $24,000
$24,000+ (650 times 4)
$24,000+ 2,600= $26,600
Money for attractions and food (estimating here): $5,000
$26,600+5,000= $31,600 (around this)
$31,600=2,466,443.2 JPY
Is this correct?

Answer:

Correct or incorrect. It depends on your real plan. We don't know what kind of plan you really have. So we can't judge.
