Travelling while keeping crypto in a hot wallet on phone?

I am travelling abroad very soon, and will stay at a camp where they have their own wifi that I will be connected to most of the time, around a month that I will be staying there. If I keep crypto on a hot wallet, will it be safe likely? What if I get a VPN, will that make it any safer? I may need to connect to airport wifi as well, I am very nervous about what to do but I need it with me. I am absolutely certain that I need it with me to travel and I thought about bringing my cold wallet with me but it seems riskier taking it through customs and such with me the whole time to a new country. So can I trust their wifi, at a camp and is it likely they can somehow hack my hot wallet and steal my crypto? I am considering getting purevpn but am not sure if it would be helpful at all with this.
