I would go to the parks each day but you need to ask yourself and your mom what your are looking for in your trip. Your mom might not want to run around commando style. IMO if you are staying at a nice resort then enjoy the amenities. Are you going to go back to Disney world anytime soon after this trip? We go every feb to see the sun again. I find that takes away the stress of “we must ride everything this trip”. The parks are great but so is pool time and relaxing.
