Hello Laura
First of all welcome to the community. You have made that all important first step, and you could not have made a better choice than Just You.
The first thing to understand is that although it is a company that arranges holidays for solo travellers, you will never be alone and you will be very well looked after.
Cindy has given you some good advice about how to pay for a holiday. Only you know what you can afford so I will not advise you to go anywhere in particular. Pick what you want and book it as soon as possible (new brochures should be available in September). Book any extras that you may need such as insurance, excursions and possible visas etc. JY will arrange all these for you and add it all to your account.
Then after paying your deposit you can drip feed the outstanding balance into JY. That way you will not be landed with a possible hefty bill
when the balance needs to be paid.
Happy holidays
Peter
