$300 per room X 10 rooms = $3000 per day.
$3000 X 365 = 1,095,000
If it is occupied 75% then
1,095,000 x .75 = 821,250
You can deduct expenses after that and you get number closer to what I think is reasonable. Also keep in mind they are selling rooms > $300 per day so this is reasonable conservative estimate.
