Will adding my own access point on top of the hotel's wifi make it more secure for me?

So I'm traveling, and I have a tp-link n300. Wondering if me connecting it directly to the ethernet port in the hotel, then creating my own access point makes it any more secure?

If not, what are some practical ways to make it more secure without a vpn?

Why without a vpn? 1.Internet speed isn't great to begin with, adding the vpn just makes it way slower that it's completely unusable. 2. I rented a room for a month, and connecting each device to the vpn upon reconnecting is really annoying, and disconnects many times.

Btw, I have AirVPN

Maybe an extra hardware or an extra layer of software? Some configuration?

Thanks a lot in advance!
