The details of your parents visit (whether or not you entertain them properly, etc) don't matter as much as your feelings about them and their visit - guilt, anxiety, pressure to entertain, fear they won't love you if you don't deliver, etc.

That said, maybe you could set their expectations up front, before they arrive, and be honest - something like 'I love you both but I am having some fatigue issues and won't be up to our usual daily trips out'. Then maybe you can set a schedule that works for all of you. If you mom puts the guilt stuff on you, it will give you an opportunity to work on yourself and get stronger in navigating relationships in healthy ways. I always need help making these type of changes - when you feel weak, call a friend who understands.

Hugs - family is our biggest challenge.
