Help! Lifestyle vs Niche Blogging

Hi Fellow Bloggers, I need your help. I can’t decide if I should continue with Lifestyle Blogging (but recently writing more about Travels only) or just focus on Travel Blogging. And if I will continue using my current blog and domain (Oh My Glai! ohmyglai.com) or open a new blog (Trains And Thoughts trainsnthoughts.com). What do you think? Your comments will be appreciated. Thank you so much! 💕
