Rooms with two double beds have long been standard here, meaning you’d have to go out of your way to find a place without family-friendly accommodation. Big cities such as New York can be expensive hotel-wise; otherwise, despite the current strength of the dollar vis-à-vis the pound, hotels aren’t too savagely priced. In Alaska, we recommend the Sadie Cove Wilderness Lodge.
However, as elsewhere, you may choose to save money by opting for some form of self-catering accommodation, such as an apartment or even a house (read our feature on British–US home-swaps). The US landscape and the vast distances involved in exploring it also make motor-homing a popular option.
