can you take 20 kilo suitcases on ferries from Kowloon to Hong Kong Island.

Staying in Mongkok, and as next part of holiday is on HK Island. we thought it would be nice to catch ferry across but we have our large suitcases and even though Stanford Hotel will drop us at Ferry Terminal and we can catch a taxi to Hotel Jen, we don,t know if we will encounter stairs and escalators that will not be suitable for wheeling our bags. Hope to hear from someone who knows. Antoinette
