I was just there last week and it was $30 for 2 chairs and an umbrella ($10 each). When we first got there, they had no chairs or umbrellas available so we had to wait for people to leave to "claim" them. Felt a bit stalker-ish, but the UV index was 10 and I burn easily so I REALLY needed the umbrella. Horseshoe Bay is beautiful, wish I was back there. Enjoy!
