Umbrella, bug repellent, sunscreen, rainwear, travel pillow, walking shoes, pen, and small backpack or tote should be added to the packing list. Additionally, beach towel, hat, sunscreen, swimsuit cover up (for women), UV protection clothing, water shoes, float(s), and pool toys should go under swimming and beach. Beach could also use beach blanket or mat and beach umbrella. International could use foreign language book and pen. I see people asking for a pen to fill out the entry and exit forms on a plane all the time.
