We're going to meet GF's parents in Vegas this spring/summer for a quick trip. We found rates at the Luxor for $80 a night over memorial and Tropicana for $55-70 at different times in May and June. So we could save $45 tops by staying at the Tropicana, but likely less. Which would you choose? I know the Tropicana's pool is supposed to be better and the Luxor's buffet is better. Anything else we should know?
