My wife and I will be on the BI next week for our 30th anniversary. We are staying at the Marriott Waikoloa. Originally I planned a whole day for VNC. By whole day I mean leave early AM and back at the hotel before dark. Now I'm wondering if it's worth an overnight in Hilo so we can catch the lava glow at night? Also is the glow best viewed from one of the hiking trails? If so do we need a guide or just tips from one of the park rangers? Thank you very much for any helpful information.
