Since you were asking questions in advance of your skill test in April this year, I think it fair to assume that you are a low hour pilot. Since you appear to be asking whether you can fly in unfamiliar airspace solo, then it follows that the answer must be no! not without several hours familiarisation, the decision is up to the CFI of the place where you want to rent the aircraft from. If said CFI says you need more dual time, then you need more dual time! Even an experienced pilot should expect a couple or four hours local familiarisation when flying in a country which he/she has no previous experience of. No doubt if you have the cash then the CFI will have the patience to get you solo!
