Quick answers

What are the most unusual types of hotels in the world?

StayAtNiche covers 14 types of unusual stays: treehouse hotels, cave hotels, underwater rooms, castle hotels, bubble hotels, floating hotels, cliffside hotels, desert camps, ice hotels, jungle lodges, safari lodges, overwater bungalows, lighthouse hotels, train hotels.

Are unusual hotels more expensive than regular hotels?

Not always. Prices range from around $100 a night for simple cave rooms and glamping domes to $1,000+ for underwater suites and private-island villas. Each listing shows a typical nightly range; always check live rates for your dates.

When should I book a treehouse, ice or underwater hotel?

Book 6 to 12 months ahead for peak seasons. Ice hotels are seasonal (roughly December to April), aurora stays fill up early in winter, and small properties with only a handful of rooms often sell out first.
