Home or holiday property
At a rental property, get the owner's written approval before booking and confirm there is suitable access, a level base, water and power.
Choose for comfort
An 8 person tub is the usual choice for adult groups, although six adults generally gives everyone more comfortable space. For a larger party, rotate sensible sessions.
Keep the weekend safe
Keep glass away, nominate a responsible person, follow the temperature guidance and never combine excessive alcohol with hot tub use.
