Sidenote for x2 evolution spotlight hour: Make sure you return to the map screen before the spotlight hour ends/before your lucky egg expires or you will NOT get the bonus exp. I learned this the hard way as I assumed the exp drops as soon as you hit evolve. It does NOT! The exp stacks up and drops as soon as you return to the map screen!
Glad it's been working out for you! 2x evolution spotlight hour is such a low effort method and accessible to even f2p trainers. One of the lesser utilitzed methods that really do pay off.
