With most Hotel/Motels if there are more than 4 persons in your party then you would require two rooms as they generally only sleep 4 (or a fifth person on a rollaway bed) with no guarantee that the rooms would even be next to each other.
Hotel/Motel room rates are as low as £30 ($50) per night plus 13% tax of £3 ($6) and this would work out at £66 ($120) per night or £462 ($854) per week for two rooms.
Most rooms consist of just two double beds and a bathroom.
Most have community swimming pools.
