My son was home from college during this winter break. We went to Disney World for 10 days while he was home. We booked a hotel where he could work out in the evenings or early mornings before heading out to the parks for the day. While finding a place to throw a bullpen was tough, he kept up with throwing and strengthening his arm by ways of throwing a football while we were there. We would come back to the hotel during the day and find an open area in the parking lot and throw the football for about a half an hour. I did pack the TAP training sock in case he wanted to throw around the baseball in the hotel room, but football was a better option. He went back to school right after vacation and said his arm feels really good right now.
