Airlines will usually require a health certificate of some sort, and proof of vaccination. You may obtain these from your veterinarian. You certainly don't want to find out checking into your hotel that they have changed their policy and don't allow pets. If you do take your dog to campsites, beaches, and other such areas, be respectful of the other people around you. Simple common sense and courtesy should ensure a good time will be had by all.
Many veterinary offices provide boarding services as well.
Regardless, be sure that the boarding facility requires all dogs to be currently vaccinated, including kennel cough. If your vacation is over a major holiday, make your boarding reservations well in advance. The large boarding kennel in my community is full 2-3 months in advance for holiday weekends. Another alternative would be a pet-sitter. This is a growing field of animal care.
