Kintetsu Rail Pass

I will be travelling from Kyoto to Kintetsunagashima in Dec. 4. According to Hyperdia, the train journey requires transfer at Yamatoyagi. Since the rail pass allows only 3 limited express journeys, does it count as a single or 2 limited express journeys?
What is the bus schedule and cost from Kintetsunagashima to Nabana no Sato?
What time is the LED light-up at Nabana no Sato?
The winter ticket price at Nabana no Sato is 2,000yen. Can I purchase a ticket at 12.00pm and stay till 9.00pm?
