I'm also a first time traveller, asking the same questions, also travelling alone. I'm planning on going in may, so 2 months later than your plan.
I'm a guy 25 year old, will be 26 when travelling. I wonder if you would like to chat and maybe go together? I'm terrified of travelling alone!
I realise you might be reserved about an offer like that from a random guy, but give me a chance. Feel free to either ignore this or follow it up with a message, your choice completely :-)
