5 days is better than 4! Try the Treehouse to see if they can give you a Groupon like price. You are 1 day into high season but should be able to get something. Also Coco lapalm, Country country, check out the specials on the hotel section of this site. Must do, for a 30 yr old birthday, is One love pub crawl a blast where you'll meet lots of people and see a great slice of the West End. Always try to get a "Drifters" jam session in on a Friday or Sunday afternoon. Since you have a direct flight from YYZ five days is a breeze. I have done a long weekend. I really recommend Club Mobay for a short trip and it pays for itself on the departure especially if the flight I'd delayed. We will overlap one day with you and a birthday drink is not out of the question. Enjoy and feel free to ask any questions here. Someone will be able to lead you right!
