Congratulations to both posters on clearing the debts!
Now, I was in the same position last year - finished my contract, still had a student loan (that's a whole other point of debate) and was going to take the trip/travel/pilgrimage before ordaining.
Went to WPN and a few other monasteries in Thailand, spent plenty of time with monks, bent lots of monastic ears and got some great advice for ordination. Speaking of which, nearly all of them said not to use such a trip to go 'monastery shopping' - you'll never find the perfect place.
Then I went to Burma. Thanks to long-standing family connections and my inability to say no to the chance to meet new people, I'm now living and working here because the nature of the country in this period of huge transition and watching international reactions and actions has utterly gripped my curiosity and interest. Every day here is an exercise in awareness, patience, understanding, empathy and development of my sila and metta, which is very hard to do sometimes. It's also the opportunity to witness and experience types of dukkha in myself and others that I never knew possible (the dukkha arising from no electricity when the temperature is 39c, water that runs brown and showers that leave you dirtier than when you stepped into them, combined with a stomach bug from eating badly prepared food and uncertainty as to whether immigration might one day find a 'problem' in your paperwork - makes first world dukkha look desirable by comparison but still doesn't compare with the myriad dukkha of even greater intensity endured by locals on a regular basis, such as having enough money to eat at all etc.).
I sure as hell wouldn't ordain here (Western Sangha for me), but I'm currently content as a lay person here and the experiences, challenges and opportunities for development of my mind and practice that life here brings. As and when that changes, I shall resume my path towards monasticism. Ironically, I can't do meditation retreats here on my current visa.
Has this diminished my desire to ordain? Kind of - it has certainly taken the self-imposed pressure and intensity off that would have likely caused me problems had I decided to skip the trip and ordain because I felt there was no other way to spend my life in a way that was conducive to meaningful practice, within the exceptionally narrow sphere that was my 'life'. You can bet that, as and when I do decide to ordain, I won't be as insufferable! I've let myself relax.
So definitely take the trip, and also remember that, as your life circumstances change and your experience and access to parts of the world you could only ever imagine starts to take shape, you may find your desire to ordain will be tempered with your interaction with the world and others around you in a way that remains skillful, beneficial and not self-indulgent. You will have different challenges and learn different lessons compared to life in a monastery as an anagarika/bhikku, of which you will form your own view as to the utility of these lessons in the overall 'big picture'.
Therefore, my advice would be that you take the trip with the full intention of ordaining, but don't try and live or act like a monk whilst you're travelling. Whilst that doesn't mean indulging in hedonistic sprees such that certain demographics of traveller are notorious for in this part of the world (I didn't and had no desire to and still had a wonderful time), do allow yourself permission to take advantage of opportunities to meet new people, deviate from your itinerary, travel to places you hadn't planned to go to and do things that don't center around Buddhism, monasteries or the Sangha. Personally I had a nice blend and had a wonderful time, I have a great distance friendship with the Luang Por in the UK who was (may still well be) going to be my Preceptor and have Sangha friends locally who love meeting up with me and discussing dhamma as well as practicing their English, as well as a busy and fulfilling lay life. I'm pretty content right now.
Finally if, like me, you do end up on 'extended travel' don't see that as an abandonment of monastic aspirations and - with it - all that you stood for and held dear. Instead, see all this as part of the (sometimes winding) path.
