Travelers checks are not advisable because there are only a few places where they can be exchanged for money and the exchange fees are high. Spread your risk, disperse your money throughout your garments inside a locked suitcase and some in a leg stash on your person. Remember the amounts in each location, and when making purchases, only retrieve the amount of money needed for that purchase. If possible, take a Polaroid camera and plenty of film with you to the socials and take a picture of the ladies whom you are interested in. You will meet so many ladies that after a couple of days you will forget who you met on the earlier socials.
Weather is often unpredictable and can get very cold to extremely hot in the middle of the summer.
Spring and Fall are typically cool to cold and it can even snow, so prepare accordingly. Take a comfortable pair of sneakers and jeans to beat around in, you will not look out of place. Do not take your expensive watch and expensive or flashy jewelry. High quality cotton T-shirts with either Disney or college insignias. But, keep in mind that Russian and Ukrainian ladies typically enjoy small but thoughtful gifts more often than things that have a significant monetary value.
