Comfort Suites near Spanish Springs is a pet friendly hotel. We stayed there last summer with our two dogs prior to our closing and were pleased with the size of the room and the hotel.

One item you should do is the free trolley ride at Lake Sumter that takes about a 45 minute tour of The Villages. Taking in the evening entertainment in both town squares would also be recommended. Enjoy your visit.
