Coney Island - Coaster hours

Quick question (sorry if it's been covered, I couldn't find anything with a search):

I see that Luna Park is only open on weekends in April, but according to Google, The Thunderbolt has daily hours now (March). Is Thunderbolt (and the Cyclone - once it reopens) available to ride even if Luna Park isn't open? Just looking for clarification on conflicting info. Would love to be able to plan a daytrip while we're there in late April. Thanks.
