Can you take perdiem when traveling overnight to an owned rental?

[Randall Marshall]

If I travel 400 miles total, log the miles in my logbook, and have an open house for a rental property, stay 1 night in a hotel, and drive back home, are mileage, lodging, and meals deductible? I've been reading that only 50% of meals are deductible but can I instead simply take the first/last day per diem amounts listed on GSA? Do I still need to keep receipts for meals and lodging?
