You may have some success with 4G connection. 4G connections are not created equal and some can have fairly low latency. Worth a try if you get a data plan, have leftover data, and have good connection.
Try to find a wifi source for major system and application updates. I just did a 1 GB plus OS update to my laptop on my home cable connection. No point in using your 4G data connection for that.
Faster 4G connections tend to be in more urbanized settings. I just stayed in Crystal Cove state park and had excellent 4G. Zion has good cellular signal in Watchman Campground can't remember if 3G or 4G. Mammoth Lakes has excellent 4G in Shady Rest campgrounds. Check your latencies and if you have data to burn it is worth a try. I doubt you'll have to give it up cold turkey. I'm not expert on gaming but you may find 20-40 ms 4G latencies in urban areas, or parks adjacent to urban areas under optimal circumstances.
