My wife and I are planning a four or five day vacation to the Portland area at the end of July. I really like the idea of staying lakeside (e.g., Sebago lake) while doing all the" touristy" things in and around the city. That might mean spending a typical morning at the llake and coming to town in the afternoon for a dinner and show. Is it feasible to enjoy the city/scenery using a lakeside rental as a base of operations? We would have a rental car. Thanks.
