Congratulations on your growing family! Traveling with 5 is definitely a fun challenge.

Here's what works best:

• Airbnb/VRBO — honestly the best option for family of 5. Full house, separate bedrooms, kitchen, much more economical than 2 hotel rooms
• IHG properties — good choice! InterContinental and Kimpton are indeed flexible with families. Holiday Inn also great for families at more budget friendly rates
• Marriott — their suite properties work well, look for Residence Inn or Element brands, they have separate living areas and kitchenettes
• Connecting rooms — always request when booking, call hotel directly and explain family situation
• Suite hotels — Embassy Suites always includes separate living room, great for families

For newborn specifically — most hotels don't charge for babies under 2, so you're fine there!

As your kids grow older, Airbnb becomes even more practical and economical. Enjoy your travels as a family of 5!
