Doyle, 31, is set to join the Colorado Rapids in the summer when his Wolves contract expires, with the two sides confirming the deal last month following several weeks of negotiations.
As well as taking a trip out to the States, the Republic of Ireland international also sought the advice of several clued-up individuals ahead of agreeing to the deal, including compatriot and LA Galaxy captain Robbie Keane and the recently-retired Hahnemann, who spent two seasons with the Rapids before leaving MLS for Fulham in 1999.
During his 13 years in England, the ex-US international goalkeeper was teammates with Doyle for four seasons at Reading, helping the club seal promotion to the top-flight in 2006 with a record 106 points, before both moved on to Wolves together in the summer of 2009.
Later returning to the States in 2011 to see out his career with hometown club the Seattle Sounders, the Washington-native was thus one of the first people the soon-to-be Rapids star looked to for guidance before deciding to take his career across the Atlantic.
“I spoke to Marcus Hahnemann, who was my roommate at Wolves and I played with him at Reading, and he was telling me that Seattle Sounders are like an English team with the fanbase and the atmosphere at games and a lot of teams are similar now,” said Doyle.
“There’s big teams, big crowds, big stadiums, it just seems to be getting bigger and growing all of the time. And there are new teams planning to join from what I hear, so it’s on the up.
“Outside of football, there’s the lifestyle and moving my family to the other side of the world but it’s not like it’s a different language or anything, we’ll settle in pretty quickly. I just want to get on with doing those things and get started.”
One thing Doyle which will have to grow accustomed to in MLS is the travel, with the Irishman set to face some long flights for road games, including a 1,300-mile trip to Toronto in September.
However, having struggled to get into the first-team pictures at Wolves over the past two seasons, the 61-times capped forward is just looking forward to the chance to prove himself on the pitch again.
“It’s all something that within five or six weeks you’ll get used to,” he added. “Obviously at the moment, the furthest that we go to an away game we’ll be on the bus for maybe three hours maximum, so flying to away games will be a little different but you just get used to it.”
