Hi! I will be visiting in mid-September for one week and looking for a vacation rental. We would like to swim, or at least play in the water. Is Lake Michigan too cold? Should we find a rental with a heated swimming pool? Also, which beaches are best from New Buffalo to Saugatuck? Any suggestions for vacation rentals? Looking for a laid back, friendly area with plenty to do in terms of sunny and rainy day activities. Would like to be close to town, although don't necessarily need to be IN town. Thanks!
